200a ~ 3/0

I don't think a "Clipping" on to a Al. neutral bar is a good idea IMO.

Probably...all of them :grin:

Considering that all ckts are now essentially GFCI or AFCI ~ who cares...the ckt's neutral goes right to the CB...the clip on the CB is making contact with the neutral bar.


I could be wrong on the configuration..I haven't RTFM :smile:

..but "clipping" onto an ungrounded conductor bar/bus is acceptable?

i say the more wires that connect to a cb the merrier. besides added functionality it looks neater.

Yes, I don't mind losing power on a MWBC, It's losing the grounded conductor
I'm worried about. Panels that are located outdoors, the Al. bus bar is
going to oxidize and cause problems. Great for us, but as a design I think it's a bad idea. Just look at it, does a clip over a mechanical screw look
like a good connection that will last over time and load? It's just something
I wouldn't sell or recommend when my name is on the install or design
choice, Listed or not. JMHO

That's my thought too....whatever is the largest conductor the meter pan can handle.


...but why?
I don't understand.:-?

I got one for you. Would you prefer 2/0 cu over 4/0 Al ? I would prefer the 2/0 cu for a SFH

Is there any point in ignoring T310.15(B)(6) and installing 200A services with 3/0 CU conductors on a typical SFH?

I had an inspector tag a service. He said I used the wrong size wire. I ask for the code he has in front of him and get him to the page# with the table. He said "OK, use 3/0 next time".

It's not worth my time. I stock 3/0 & 3 ga. I don't stock 2/0 & 4 ga. It's not about ignoring the table, it's about the value of my time.
