SUBPANEL AS A CHASE TO GENERATOR SWITCH

[jeramiepluemer]

WONDERING IF THIS IS LEGAL. HE IS ADDING A GENERATOR SWITCH AND USING THE EXISTING MAIN PANEL AS A CHASE TO THE NEW MAIN PANEL. THIS WILL MAKE HIS EXISTING MAIN PANEL A SUB PANEL. THANKS FOR THE HELP IN ADVANCE.

MY FINDINGS ARE A BIG NO WAY UNLESS AHJ GIVE PERMISSION

Actually there is no issue with using the panel as a chase, the issue is with having service conductors in the same raceway or cable. Fill might also be an issue in that nipple too as he was really struggling to get them all through.

Anyway to find where it says that. Thanks

I don't understand why he ran all those new wires. It would have been easier to use the load side of the original service disconnect to feed the transfer switch and splice the wires going into the house.

I saw that video a while ago. Seems the powercompany had no problem with no inspection before energized.

Does "exception No 2" cover that (as an exception)?

And no way that passed for conduit fill?? Liberal AHJ?

Are you sure? That raceway can be filled to 60% fill. At 40% fill you're allowed 5-#4/0 XHHW Al compact conductors.

I usually run (2) 2 inch. One for the service conductors and the other for the feeders.

WOW, just checked it and it passes if he was using 6 - 4/0's with the ground. Looks are deceiving...

It looks like there are a couple of 2-pole breakers on the bus from the main breaker. So if these loads don't have to be backed up by the generator then what you said could be done without an additional panel for such breakers.

I read this and I can't find where it says we can you the existing main panel (which will be a sub panel when we are done) as a chase from meter socket to main service disconnect.

not anymore

you run the wires through the sub panel which was the main panel before we started this process to the Generac t switch. sorry i am not very smart and i guess i cant read either. i just dont see where is says that.

I think i read it here. i can run from meter through the subpanel (which was the main panel) and feed through to my Generac switch as long as it doesn't exceed 8 feet in length

 

[jeramiepluemer]

sorry for asking this over and over. It is a big deal for me to get this right in my head so I can go up against my master electricians i work with. i told them yesterday what i was told on here and they don't believe me. one does but in my mind i want to understand

I'm not sure where the 8' comes in but it says you can run conductors through a panel as long as you don't exceed the cross sectional fill as spelled out.

 

[jeramiepluemer]

I was told from meter to panel it cant be over 8 ft
