I have a situation where I am wiring a home with a detactched garage in the back. The service will be mounted on the garage and I was going to install a 150A meter/ main that has an 8/16 panel and feed thru lugs. Then we are going to go underground to the panel on the house. I was having trouble locating a 150A MB panel with higher capacity than 30 circuits so I was going to install a 200A 30/40. It seemed an odd installation so I called the inspector just to get his OK before I ordered and installed the equipment. He checked with the asst chief who said no but couldn't cite a code article. The way I look at it is the panel is protected upstream at 150 and the MB on the house is essentially just a disco switch so it's rating doesn't matter much. What am I missing?

(I know there are other configurations that I could use to get this situation to work (MB kits on MLO panels etc) but I was looking to get this stuff ordered and installed out of local stock as time is a bit of a concern)
 
you have some options with square d.

homeline convertable panel + QM2 150a main
qo convertable panel + QM2 150a main
qo MLO panel + backfeed QO2150 breaker (eats 4 spaces)
 
I'm curious as to how the inspection department can say no and not provide a code reference?
 
Someone is going to have to tell me how to quote multiple posts in one reply.:smile:

-why not use a disco on outside and a MLO panel?

It's an exterior panel.

-you have some options with square d.

I'm trying to work out the details as to what's available.

I had the same thought but figured it was futile arguing with the foot soldier. I've got a message into the chief inspector.

homeline 40 space exterior panel main lug convertible to main breaker
p/n HOM40L200RB

QM2 150a Field-installable Main for convertible main lug panel
p/n QOM2150VH

QO 40 space exterior panel main lug convertible to main breaker
p/n QO140L200GRB uses same main breaker above

QO 42 space p/n QO142L225GRB

if for some reason you must have 42 spaces in a homeline, this is 225a 42 space main breaker p/n HOM42M225RB then you can replace the main with the breaker listed above
