Channel letter wiring

We use wire nuts, you could use other connector if you want.

 

I used to use these when I did electrical work on oil rig/drilling equipment. These things are amazing and stood up to a lot of abuse. UL listed. Assuming they are allowed in signage.

That's the problem with this post. It's a bit of a silly and scary question considering that he should already know codes and be versed on how this stuff is done. If you have to ask, you shouldn't be doing it.

 

I'm assuming your talking about 12v DC?

12 is too much... I've seen people do 10 or 12 on one large wire nut and it looks like a sloppy mess. Split it up and make it manageable... I don't like having more then 6.


And on a side note... why are people wrapping lamp sockets with masking tape??

 

If it's 12v use that terminal block with jumpers or a stud. Terminal blocks really just make diagnosing problems easier. You cant load up 12 wires on a wire nut, even 12v will get hot and start a fire. I'm not real crazy about wire nuts with stranded either but this is out of my AOR. Those stab in connectors banner posted work well if youre doing production work

 

crimp nuts on our repairs

 

If using the regular jacketed wire, get some 12 ga non jacketed and some scotchloks, run the 12 ga behind the wall the length of the sign, tap into it with scotchloks behind each letter, throw the wire nuts at unsuspecting individuals from your bucket truck.
If you're asking how to put 12 wires in a single connector, you're not qualified to do this part of the job and need an electrician to show you the ropes.

 

The masking tape on the lamp sockets keeps the bulb from bouncing loose in transport.
