This is a great message. Err on the side of caution. Period. Electricity is under no obligation to do what you think/want it to do. Grounding and bonding ensures that electricity has no other choice than to go to the safest place. Safe electrical practices reduce the risk of accidents, injury, and death. Keep doing the right thing!
Glad that you mentioned that they don’t have to be green. I’m in Canada, any devices I buy have green grounds but the boxes I’ve bought whether for devices or junctions all have raised grounds complete with screws but they aren’t green. Thank you for sharing your expertise.
Actually using a pigtail to bond the box, as you demonstrated is the only code compliant method of bonding the box. 250.148 (C) Metal Boxes. A connection used for no other purpose shall be made between the metal box and the equipment grounding conductor(s) in accordance with 250.8.
In the new barn build i bought the pre made pig tails with the ground screw, was nice to have them all made up and save a little time while using the rented diesel lift. Also used the "greenie" cap connector that allows the bare wire to come out the tip.
Wrapping the ground screw, or any screw attached to the box is perfectly fine. However, I would caution against wrapping it all the way around so that the ground wire overlaps itself underneath the screw. If you do this and over-torque the screw, the wire can actually break off, which is no bueno.
At 5:00 if you are overlapping the wire when going around the ground screw it is not code compliant. 2011 NECH et al. Exhibit 110.14.(diagrams), overlapping is not permitted.
Hi, thanks for the video! It is really helpful. I have a one question for you. I am trying to install a dryer outlet and I know I need 10-3 nm-b wire for that. I also want to use a metal box so I'm going to ground the box like you showed. but I am curious if I can use 12 AWG Solid Grounding Pigtails with Screws from Home depot. is it okay join the ground wire from 10-3 nm-b wire with 12 awg grounding pigtail?
I believe that the code reads that you have to stick with the same size wire that you pull for the feeders. You can use a fork terminal to go under the screw. It would be a yellow fork terminal.
My opinion is that if it's only the device and you take that plate off with the device then the potential for box to become energized is there. I prefer to have it fully redundant so there is slim to no chance of a shock.
If the insulation on one of the hot conductors is damaged it can arc to the box or if a hot conductor touches the metal box that is properly grounded it will trip the circuit breaker. Both the switch and/or receptacle and the steel box are grounded so if there is an issue with any part of wiring/switch/receptacle in the box if done properly it should trip the breaker.
@@MountaineerOutdoors perfect! Thank you! I also have a question about hardwired smoke detectors. I have to add another on on my existing circuit. Can I just add a 12-3 to anywhere in that circuit and run it to the new detector? Do they work off a three way splice?
New light fixture..out of the wall two blacks, two whites, two bare grounds all twisted to each other and capped, light has a ground, green screw, black and white. Do you take the two twisted grounds and combine it with the fixture ground and put them all under the green screw, and toss the screw cap? Or should I let the electrician do it..? I’m impatient from a Disaster recovery company that really, really sucks at taking months to do basically just a few hours of work, and them scheduling the electrician has taken more time than anything…
@@MountaineerOutdoors nope. I detailed all the work that wasn’t done to Farmers insurance and..they are apparently giving the contractor even more money. It boggles the mind..I’m starting to look up which agencies to report insurance fraud to…
My house is about 25 years old.There are no ground wires only red and white inside metal conduit. First of all is this safe? Or should I run ground wire throughout which would be a PITA.
Well back in the day, they used conduit as the ground. Not many people do now but it's still legal. I would say that at this point it's your call. My opinion, I like to have a redundant so I'd run the ground. I'm guessing though, your conduit is acting as the ground though. Make sure it's intact and maybe just use it.
My extra precaution is to never use bare copper wire for pigtails. I always use green wire. Just having a bunch of springy bare wires that might be pushed against the connectors on the device makes me nervous (and I usually wrap the device with electrician's tape!).

My pleasure thanks for watching and commenting ☺
Currently working on a DIY project. This gave me peace of mind as I was just second guessing if I was going overkill on the boxes I’m setting up.
Good luck with your project and glad that this helped you

Exactly
@@MountaineerOutdoors I didn’t know that either. Went back and added pigtails to three other boxes I had already installed

They definitely are a great little item to use

It most certainly is code compliant. Might need to check that again
@@MountaineerOutdoors Go online and search for the exhibits(pictures) I specified and you will see.
Saving money when cutting corners while breaking the code will actually cost more money in the long run!
california every box has to be box has to bround by code in california ground

What is the reason to ground the box instead of connecting the ground directly socket. I'm learning about electricity.

I agree 100%
Do you err on the side of caution? Cause I couldn’t get that bit clear???
😂 😂
@@MountaineerOutdoors good video brother
I appreciate it man
If you remove a wire out of that box how do you plug the hole?
With a knock out plug filler like this one. Or you can use plastic ones as well amzn.to/433bKVR
@@MountaineerOutdoors perfect! Thank you!
I also have a question about hardwired smoke detectors.
I have to add another on on my existing circuit. Can I just add a 12-3 to anywhere in that circuit and run it to the new detector?
Do they work off a three way splice?
Self grounding outlets
Definitely one way
how to you ground 220 to a metal box?
I personally wouldn't want to do that. 😂 😂 No I know what you mean but it's the exact same way

Codes are for the lowest denominator of idiots. I'm so glad the place I live only has electrical and septic for new construction.
Code is what you need to follow at the very minimum. Always do better than the code if you can btw where do you live
