Splices in panel

Re: Splices in panel

Guys, don't overlook the "unless adequate space for this purpose is provided" section of that sentence. As long as there is adequate space, even conductors that are "just passing through" may be so spliced.

This is done when adding a non-whole-house transfer switch to an existing service. We're not required to remove the home runs from the main panel. We ust route the utility current to the transfer switch and back.
 
Re: Splices in panel

I agree with Larry.

I have seen it done that way too, it is not uncommon.

EDIT: But then again, there will be those who pull them from the panel and set jct box above the panel and route the conductors into the transfer switch enclosure. They often reference that all feeders must originate form the same panelboard. :roll:

Okay, okay. I know that I can be dense sometimes, (as well as argumentative and stubborn) but tell me this: Why would a junctioned conductor be in a panel unless it was either passing though OR landing on a switch or OCP?

Edit: I did not realize there was a second page on this thread and had not yet read the previous posts.

In this case it was because of the roof top receptacles all on same circuit but entered from differant raceways.So we ended up with a splice to join all of them to one breaker.

Done it plenty of times; therefore, it's legal. ;)
 
Re: Splices in panel

I recently had a customer who wanted to modify his home electrical system so he could have an optional generator supply. After investigating his existing system, I was surprised to see that there was enough slack in the romex home runs to his basement panel that I could "simply" pull the circuits out of the service panel and re-route them to the new emergency sub-panel. Having never done this before, I was excited to be able to do it this way because, when finised, it would be the same as if the house were originally wired for the system. No splices in the service panel or anything. Well, let me tell you, untangling and removing those circuits from that panel was a real pain. I will never do that again. I could have saved myself (and the owner) at least 2 hours if I had just extended the "hots" over to the sub-panel through a nipple! Had I known what I just learned from this thread, I would have abondoned the original plan about 30 minutes in and just extended those circuits and moved the breakers! :D :D

Ram, that's one reason service changes take so long; half of the time can be spent removing trhe old panel.
