Splicing in a residential panelboard.

[kwired]

I was always under the impression that you couldn't (or should I say "shouldn't") use the breaker cabinet as a raceway even though there's no NEC section citing that.

Couldn't -- give us the code that prohibits it.

Shouldn't -- that is a design issue not a code issue.

So does recessing the panel in a wall or entering with cables or raceways from multiple sides.

I know you understand what I and others are saying, but why continue to make an issue of it? You're right, it CAN be done and most people here I'm sure would agree that it is probably not a good practice. Recessing the panel in the wall can make a panel change problematic, but there may be value in installing it in that manner.

Why? Because many of us do not agree it is bad practice.

 

[wyreman]

can't do that in sFrancisco, splicing in the panel
even tho there is plenty of volume

That is even more ridiculous than prohibiting conductors passing through a panel.

Is there a formal SF code to that effect or is it just the inspector(s) own rule

And where does this appear in the code.
I just looked at the SF amendments and there is nothing there to prohibit. You need to stand up to this make it up as you go idiot.

I am also one who agrees that it is not bad practice. It is quite common and I have no hesitation doing it.

So how many conductors or splices can be made in there?

Quite a lot if you have the patience and skills to do the math. I admit to rounding off every chance I get.

312.8 Switch and Overcurrent Device
Enclosures with Splices, Taps, and Feed-
Through Conductors
The wiring space of enclosures for switches or overcurrent
devices shall be permitted for conductors feeding through,
spliced, or tapping off to other enclosures, switches, or over-
current devices where all of the following conditions are
met:
(1) The total of all conductors installed at any cross section
of the wiring space does not exceed 40 percent of the
cross-sectional area of that space.
(2) The total area of all conductors, splices, and taps in-
stalled at any cross section of the wiring space does not
exceed 75 percent of the cross-sectional area of that
space.

Thanks!
