- We’ve made loads of videos looking at conduit bending and threading technique’s. Now it’s time to pull some wires in. In this video, we perform a conduit wiring capacity calculation. Plus we look at some top tips and haves such as using conduit lube.

Speaking as an Industrial/Commercial Electrician of 56 years, what you call 'Tabs' we call a 'Buddy Tail' in the US. I do like 'Draw-through Tape' for 'Fish Tape'. It's interesting to see how you do things, especially your 'code book'. It actually seems easier to use when calculating conductors of different sizes.
Thanks for the feedback William - we like to know how electrical things differ across the pond.
What I love about this is the authenticity of working it out with a sharpie (not a black one because you’ve lost them all) on a bit of cardboard. 😅
Use split flexi conduit for the nylon draw tape as it's a lot easier than rewinding it back in... or get some velcro cable ties.
Great gents! Very well explained! Top man
Nice job .
I normally use the draw tape to pull in a draw wire a 2.5mm or a 4.0 mm single core cable.and for cable lubrication I use silicon grease ..like the conduit system 👍👍👍👍
Great videos
Nice products
But I’m old school and still like threading and bending conduit
It’s cheaper and if done correctly is solid and stands the test of time

It certainly does. but its all about speed these days.
Picked up some good tips I have not been using - cheers guys
Great videos. Just one point though..
I don’t mean to be pedantic, but an area of square millimetres is NOT the same as that number squared (which can be much larger).
Some of us die hards still use use talcum powder as a lubricant when feeding cables through conduit .
Smells nice as well
Hand sanitizer is the lube of choice these days 😬
You can you hand sanitizer for almost anything
How much wire do you need for the socket?
Electrician: yes.
Need more of dis
Whats the best way of switching from singles in conduit to twin and earth with the sleeve? Is there a terminal box that can be used to make the joints with maintenance free wago connectors?
Spiraflex draw tape is awesome.
Could you have just run it in single core, seeing as you fitted all that nice conduit?
Or is in not allowed in pvc?
Singles are like a dark art from the past only used by Commercial electricians but they are fun too!! A bit like Tinder but for Conduit only
do gi conduit need to be grounded? if so how?
According to the regs a comon earth can be used for both circuits as long as the larger earth wire is used for both circuits in the conduit
Not a spark, but I’m sure you can use the conduit itself as earth? (Provided it’s got the correct area to carry the rated current). Think jw did a vid on it.
@@alexlovett1991
I recolect that in the regs an earth wire has to be installing a metal conduit system as you can't rely on the contact of the metal parts as over time it could corrode on the threaded parts
@@desmondyoung5963 Especially the type is this video seems like it would give a very unreliable connection. Threaded seem better if you would want to do that.
Is the conduit calc to the conduit Box or the whole run ?
It seems to me that he did the calc for the most complex (densely packed) part of the conduit between boxes. If it fits that then it will also fit the simpler parts for sure.
I have a question and I was hoping somebody would have an answer in the UK it is regulation that consumer units need to be made of metal correct? Why is it that fire panels can be made of plastic?
Fire panels don’t handle high currents so the risk of a loose connection causing a fire is reduced.
This contradicts what you said in the video on your other channel where you said you pull in one conductor at a time to avoid friction. Ie one way light loop in , in a conduit system.
Is it still permissable to use the conduit itself as the CPC.
We believe so, but not many installs use it
Seems like using an app is a lot easier... ;)
Почему нет основной изоляции кабеля?
Conduit work at 1st I used to tape bunches together that were being used together. Then woops a line is damaged had to pull the bunch out dam silly me I did think it made things easier it did on install but not for matenence. We all learn. The new as I call it push and screw fix is faster also when threading it is easy to under do it or over do it so the boxes don't align up. Also less tooling needed less to cary round. I always did see a 45 and 45 as two bends you now telling me it is one. So if I have a 45 going down running say 10 inch then a second 45 going up is it still one bend. How close dose it have to be to be only 1 bend. I know have too know the answer to that. So to picture it a straight run of 4 foot horizontal obstical is in the way so 45 going down running say 4 foot then 45 back up running back up to being horizontal 3 foot to terminal box.
Yellow 77 makes a 20mm conduit atleast 40mm :-)
why are cables cores limited even if there are space left ?
Heat dissipation during load. Cables in the middle of a group can't shed their heat due to the other cores
@@001Neal100 thank you. But what if all cables are low load
Does anyone wire without CPC anymore?
Good question 🙋♂️
standard practice these days, saves any agro of getting a high reading down the line
You appear to do the 2mm2 cable Calc not the 2.5mm2. The 2.5 is 244 not 256.
Good spot.
Pull it all back out and stick 25mm in. It ain't going to fit!
The left part is the length of the cable run in meter, not the cross-sectional area of the conductor. In that table that one isn't even mentioned. And there's no 2.0mm², after 1.5 comes directly 2.5mm².
@@Marcel_Germann True that. Steptoe hasn't got a clue what he is on about. And I'm half drunk and will go along with anything 🤣🤣🤣
Sorry ignore I am wrong
Ignore what?
@@Michael-he2nn What he wrote in his other comment. 😉
@@Marcel_Germann ~If only there was some way he could respond to the comment he was talking about.
Am i the only one who still uses a spirado?.. i find those nylon tapes a real pain not tried the yellow 77 stuff,i use the smurf goo or some talc
It's the cost of a spirado and the ability to actually get one. My last 25m cost somewhere close to £200.
It only gets used to pull in drawwires with no load on it, then back into a canvas bag(old pillowcase) and copious wd40 sprayed on yo keep it good
Granted they are expensive, but worth every penny if its used regular.. ive even cut some old ones down 5 & 10m (got stretched or kinked) .. handy for a small job
@@thattoolguy9432 expensive enough that the next time the apprentice kinks mine ill probably try out the 25m nylon milwaukee with the battery puller.
Agree they're fantastic but realistically every year I'm doing less and less pipework cause nobody wants to pay for it, and I'm doing less for companies to profit off and more of my own work as my own boss
Don't make it simple, do they? Lol!
No room for extra circuits .
Run your own damn conduit
@@cal5566 I was joking !
@@raychambers3646 no you weren't, I bet you'll still try pull a couple of switch wires in there haha
@@cal5566 no your right ,they are amateurs , tons of room in there !
I hate the actual pronunciation of con du it like English and Americans say it. 😄 I say con joot. I'm scottish.
I had a learner once who called it "condument" in a lesson. Needless to say after we'd all stopped laughing that's all it was called for the rest of the year. 😂
