Joints in panel

[storeytime]

I am finishing a residential job that someone else started. (Nightmare!) The panel is an outdoor, surface mount, 200 amp, 20 space panel. Because of the number of 240V circuits (8), there is not enough spaces to accommodate all the homeruns. I am going to have to install a sub-panel. This will make the homeruns going to the sub panel too short. Can you legally make joints in main panel. Otherwise, I'm going to have to take down the whole service, install a gutter and start over?

Yes, splices are permitted.

See 312.8.

Whethere 312.8 actually applies at all has been subject to debate. Either way, the splices are fine.

Re: Joints in panel

Can you legally make joints in main panel.

In my state, it is legal, provided you have a special license. Although, on occasion, the ATF will kick a door down on a cancer patient with a license.

You can splice in panel yes .But you can not run home runs thru it to another panel.

You have a code section in mind for that Jim?

...But you can not run home runs thru it to another panel.

Why not?

It happens all the time when an 84 ckt panel is unavailable

Not with me but what he would be doing is using the first panel as a raceway.With or without splice it isn't legal

Story, if tandem breakers still won't do it, I'd consider replacing the panel anyway, rather than subbing. Using the same brand of panel would minimize new breaker costs.

If he does it right, his wires will make it to the top of the sub panel and then splice there.

Again I ask for a code section.

Will get the friday for you.Are you saying we can use main panel as a raceway to get to another panel ? I dont think that will fly

I'm with Bob-o here....we need more than a "I say so - so it is" response.

It IS legal and it does fly.

EDIT:
Friday is too far away...here is a code book:
2005 NEC Online

OK I will be holding my breath, is Friday when your photocopied 2005 NEC arrives? :lol: :wink:

Yes.

I dont think that will fly

It won't fly, the wires hold it down but it will pass inspection if they use the NEC. 8)

Ok where do you find it saying he can ?

But it is. There are even cross-section-area fill limitations.

Added: If memory serves, it's 40% for conductors, and 70% at joints/splices.
