In a new residence being planned, we'll have a:
"MSP Meter/Main Service Panel 200A 277/480V 3PH 4W"
that will feed a 200A 3ph/4W transfer switch; choosing between the grid above, and a backup source. We have no need for any loads on the PG&E side of the transfer switch, save one: VT's & a loss-of-phase detector.
The licensed electrician has indicated 200A 480V MSPs are not available with distribution, so a panelboard will have to be added between the MSP and ATS 1.
That's $$ and space...just to tap off a few VA for the VT's.
My question is: is there an alternative? A 3-fuse fuseholder or such that's approved for this kind of application?
