Replacing a 50amp RV Shore Cord Plug

- Here is a simple task that is more than likely needed on many RVs with 50 amp service. Here are some tips I have found useful.
Technology Connections put together a good video explaining the two-phase electrical concept I did not explaing well here:
• The US electrical syst...
I have a travel trailer so my cords are all drop cords I'm able to hang in a rear closet, they're not connected at one end to the trailer permanently. I love building my own cords and cables, I've built them all and I think I've saved some money doing it. Love my cords, I always have a nice one handy. To be honest, I have never used the instructions ever for the cutoff measurements. That all changes today. To think I almost didn't watch this video. It feels like I've walked past at least a half a dozen 20 dollar bills that I just never took the time to bend over and pick up. Thanks, this is another unbelievably helpful video and such a simple lesson. Lunch is on me next time I'm in the area.
I'm happy you enjoyed the video!!!
Just replaced plug but did not cut back wire. Great info! your making my list longer. Happy RV
Awesome! Thank you!
This video will save several RVrs many $ 👍
I sure hope so. Thanks!
This was very helpful. Never thought much of discoloration of the copper , but now I know why. It's one of those jobs that I think most would be terrified to tackle on their own. Thanks man!
You're welcome!! Thank you
I cannot easily pop out the prongs. Should I use more force for them to come out?
Should we be putting dielectric grease on the prongs for better contact and less arcing possibilities?
I would not. These cords get dragged around and abused. Grease will just attract dirt and rocks. Thanks!
how can I get u 2 work on my rv
I appreciate the offer but I am so swamped I am not taking on any new jobs
I Always learn something with your videos. I didn't know you could pull the blades out to wire the plug. It'll make the next one a lot easier! Thank you.
Glad to help
Every time I'm about to do an install or repair on my Beaver, I look at your channel. I always find a video that makes it easier. You're the man, Sir. 🤩
I did this about a year ago to help a neighbor out on his 50 amp extension cord. I do have a question, since that is a power reel, there has to be contacts in there somewhere. Should that contact be subject to inspection due to the findings on the plug end? The female power pedestal contact may also be subject here also, correct? Campground power is questionable at times. That’s why a EMS system is so important beyond a surge protector.
Most power reels like this one use a winch to push and pull the cord into a basket. There are some that do have slip rings and brush like contacts. Those do tend to have much more problems.
Just knowing it was a 50 amp service I knew it was going to be a bear to change out. Wires are so heavy compared to a 30 amp wire. Nice job.
Great point!
If you look closely the screws are specific to electrical look close you will see Flat, Phillips, and Square. They make a driver that is all three ( Klein tool # 32378 ) also tip size #1, #2 and so on. I know this is an old video but. 😎
Check clean the ends with steel wool very fine file, check for colour you want it to be looking bright
Also check the pedestal that you’re plugging into, a lot of campgrounds do no maintenance or very little, I use a Hughes surge protector at every park
I"ve noticed the original plugs have crimped connectors and they seem to last about 10 years or so before going bad. I really noticed a problem when folks would try to run both ac's and their plug was hot to the touch up to as much 180 degrees. I now check their plugs with a heat temp gun to make sure they have a good plug or I make them disconnect because they just melt my outlets. I prefer the ones with hex head screws as I feel that I can get them tighter.
30 years in repair and I still can't "teach" these tasks nearly as well as you! Great explanation!
On any burned or corroded wire repair, I always just cut it back a few inches at a time until I get past the bad area before I start any connection prep.
Thank you. I'm frustrated as I can work so easily with everyone but my son, then I'm just a jerk it seems.
@@AZExpert its gets easier with kids....once they move out and start living on their own....then they start "getting it" much better. Lol.
@@AZExpert unfortunately we expect our kinfolks to read our minds and get grumpy when they can't. Take a break, toss a ball or throw a frisbee if you start to get frustrated, do something that takes teamwork, something your both equally good at, or try playing a video game with your son, something he has to teach you how to do.
I’m giving it a thumbs up even before I watch the video. It’s going to be great. Thank you
Hope you like it!
Always enjoy your "simple " projects :-)
I always hope for simple. You think I would know better by now
@@AZExpert AZ E.. May i have your email.. I want to buy parts for my toyota rv.. Perhaps you have parts or on a consultation fee .. Answer my questions and suggestions to rebuilf/model my rig
I really like your videos! I am learning a lot about RV repairs. This one I know about. I'm a retired electrical design engineer.
Thank you for your videos! Respectfully, Kevin
I'm sure I could learn much more from you, electricity is still pretty magical to me.
AZ Expert If you ask a question, I will do my best to explain the answer so you will understand. The think I loved most about my job was teaching others.
AZ Expert I thought I would take the liberty of sending you a link to the absolute best video I have found that explains how 120/240 volt single phase systems actually work.
ruclips.net/video/fJeRabV5hNU/видео.html
Enjoy!
120/240 phase is somewhere (roughly) between 179.9 and 180.1 degrees out. roughly... great vid. :) :) :0 :0
Thanks for the info!
Thanks for the video! Very helpful. I am in the middle of replacing my 50 amp. My white wire is burnt. I’m leaning on just buying a new plug/cord. Thoughts?
You can never go wrong buying new if you are not sure
Thank you for this tutorial!
Only nitpick, it's not two phase, it's split phase. There's no such thing as two phase power, three phase or single phase, but not two phase. And it's not 100amp, it's still 50amps, the neutral just carries any imbalance of current between the two 120v legs. This is basic residential electrical, and is explained well here: en.wikipedia.org/wiki/Split-phase_electric_power
you are correct. I trip over my words often but split phase is correct.
@@AZExpert Electrical is a part of my day job so I'm picky about it. :-) That said, you know your stuff and I get a lot of tips and tricks watching your videos, a few of them have even helped steer my decision on the latest trailer we bought this fall.
Reading instructions. Turn in you're man card.
I hated showing that too, but I've tried too many times guessing on the lengths.
@@AZExpert lol
this is caused more from a loose campground connection. its called a high resistance open. the loose connection basically arcs and generated LOTS of hear and melts the plug ends and in some cases, the plug and cord. a surge protector will not help you as there is no surge or high amps....just heat.
No doubt the parks have bad power and plugs. It's also because there are 3-4 roof a/cs, 120vac water heater, space heaters, toasters, coffee makers, microwaves, along with a battery charger charging dry batteries or many of these modern units. Often the loads are unbalanced too onto one line.
I agree with you in regards to the ground wire sitting on the screw threads of the black wire. I wish I could post pictures of what happened to mine. The insulation did wear out on the ground wire and cause a short. Luckily breakers and surge protector kicked out stopping anymore damage than just a burnt plug. When I wired the new plug I ran the ground wire around the outside edge of the plug so the wire does not come in contact with anything else.
Well that's disheartening to hear. Thanks for sharing.
I never realized them blades came out...the times I have talked ugly to them screws...thanks..you the Man
you're welcome!
Just getting ready to make an old 50a shoreline into a 50a extension cord for those rare occasions. You make it look *easy* thanks... 😉 OLT
Thank you, it's definitely worth making your own, those pre-made extension cords are crazy expensive.
@@AZExpert I will definitely Rewatch your video to make sure I get it right. Thanks, again... 😁 OLT
Good vid but it's not 2 phase. It's a single, split phase.
yes, you are correct!
Seems like keeping the plug clean would help extend the life of the plug.
absolutely it will help.
I chuckled when you said check for stray wires. The a/c in our 2010 North Trail stopped working several summers ago in Texas. When I opened the panel & moved the wires, SPARK! One stray filament caused grounding and a fire hazard.
I am paranoind about it.
Get spell checker
Yes, simple, but very useful content.. You are an excellent teacher/coach! Your narratives are spot on.. This is a fine work.
Thank you.
Thank you!!
Hi James, well this was a very helpful video as usual. I had my. 3 ACs on my ‘07 Navigator going and it popped the breaker on the campground power pedestal. I went out to check and the plug was too hot to handle without gloves. I inspected the plug and it looks slightly burnt and melted, very similar to the plug that you are replacing in the video. So it’s time to replace it. It’s always something. Thanks again for the awesome step by step video. Take care!
Thanks
Turning off the breaker before pulling the plug can help too.
That is always the best practice. I should have reminded everyone.
Directions? Directions? Why would I read the directions? 😂😂 oh, now I know why. 👍🏼another great bit of knowledge passed on to the masses. Nice video
😁
I’m surprised that’s not a rubber-coated plug body to absorb drops, being reeled in over concrete and gravel, and generally banging about. Seems like that hard plastic would crack under use. That’d be my luck.
That's a good point. The black ones do tend to break easier, but the yellow ones will too, and do get brittle after years in the sun. So far the only rubber ones are the original ones, and a new shore cord is $200 or so
The earth wire going over the screw on the netral side is a bit bodgy hey ! , you think they would have a space for the green wire to run with no metal contact to the other wires ,, Great vid buddy ,,,
R.J.T Traveling the east coast of Australia ,,(Bloody hot 34c here today )
Agreed. The insulation is thick and there shouldn't be rubbing, but it still seems wrong.
What about putting die electric on the ends, would that help, especially if you are parked for long periods of time?
I think it would tend to attract dirt and rocks
Nice. Thanks for this video James. Happy trails!
Thanks for watching!
This video reminded me I need to do this. I agree that the yellow kind are more durable. As usual job well done! I've said it b4 and I'll say it again, your channel is going to be huge one day! I will be watching! Thanks!
Thank you so much, it's already so much bigger than I had ever dreamed of.
At least in the us you keep the same colour wire, us in the uk ares all changed to match European rules
I still have to google what blue and brown mean when I get motors or components with that color code.
It's 120° out of phase but whatev's. Not really 100 amps, I think it's better to think in terms of available watts. A 120v 30 amp is 3,600 watts versuses 240v 50 amp 12,000 watts. Huge difference. Really you need to unspool all that cable off the reel so it can dissipate heat especially when running three A/Cs. That and worn out pedalistal receptacles don't help, either. Great video and truth about cutting the conductors to the right length so you don't end up with a janky plug.
Though it is technically 240, all the circuit remain 120vac on most 50amp units. Very rarely there is a dryer, water heater, or other large appliance running 240, but yeah rms and wave forms and the such throw my mind for a loop, DC makes more sense to me compared to a circuit going back and forth really fast.
Sailor John Boy Mostly correct statements in your comment. I especially liked that the cable should be Mostly fed out. Can causesome heating of the cable. The incorrect part is the 120 degrees. In three phase they are 120 degrees apart. In single phase, is is single phase. No degrees apart, no out of phase. Most believe they are out of phase, but that only shows up on an oscilloscope because of how it connects.
would love to see a review from you on the smartplug...is it worth the extra money...
although its better, its not a cord you'll pickup anywhere if you lose or damage it, so I don't see it as a overall benefit
Oops guilty for not following directions.. thanks for the tip 🙂
It took me awhile to figure it out....like way too long.
I always learn so much , thanks for the video, this was very informative.👍😎
Glad it was helpful!
Great call on the overheat
Any need/benefit to silicone seal the inside edges of the replacement plug?
I don't think so, water would probably get trapped it in and replacing it would be much more difficult
That is a common problem. Lot of it is caused by the poor condition of the parks power pedestal. Many of them are wore out and the loose connections heats up the plug and (can) ruin it, like that one. My coach is older so it came with a external cord that you had to take out and screw into a connector on the side of the coach then plug in. I put in a Glendinning power reel and an updated onboard surge protector, that also will let me know if the power connector on the pedestal has problems. Works so much better.
I installed a tranformer surge protector on this unit as the owner was having power issues. With three A/Cs running, I could not touch this plug. That's when I noticed the cracking plastic. Thanks!
@@AZExpert I forgot all about that, I got the transformer on mine too.
I'm learning so much from your videos. Every single vid is a lesson in how to "do it right".
I really appreciate your channel.
I appreciate that! I firmly believe that I should do the work to the level I would expect it done for me at least. Which can cause problems, when I think some people's cosmetic concerns are just fine and not worth addressing. ;)
@@AZExpert I get you my friend. I get you! ;)
Follow the destructions otherwise it all goes wrong
sure does seem to
You are very good at repair of lots of things
I try my best, RVs just force you to learn so many different trades and skills.
Thanks again...✌🏼✌🏼👍🏼👍🏼👍🏼👍🏼
Always welcome
Great info and instruction. Thanks
Glad it was helpful!
great job.
Thank you!!
Good job bro.
Thanks
Nice
Thanks
Too many ads.
sorry about that
Jeeze don’t worry about how interesting you think the topic is James. Keep doing it. You could make dumping the black tank interesting.
I’m on several rv forums on Facebook and I share your videos when they’ve posted a problem I know you’ve covered. I hear references from others mentioning you as well.
I’ve even seen an winnebago owner do a video on how he screwed up by using Dicor to seal his roof. He subsequently went to silicone after watching your video. He gave you a shout out.
If you wonder if you’re making an impact on helping us rv’ers become self reliant I would say the answer is a big fat yes
Thank you so much for the support and getting the channel information out there.
