ECN Forum Forums General Topics of the Trade General Discussion Area cost to put in a new 200amp panel

Converting to single-phase sounds more like a downgrade, doesn't it?

I mean...

208V * 200A * (Sq. root 3) = 72kVA

240V * 200A = 48kVA

The only reason you'd need 3-pole breakers is for 3-phase equipment. Just have to make sure all your motor loads are rated for 120V or 208V.

Also, many 3-phase panels have feed-thru lugs. Would be a shame to have spent the time/money to replace the panel if it was just a matter of piggybacking the new panel on. (Providing the existing installation was sound.)

It makes me wonder if the power company has both 3phase 208 and 1phase 240 on the same pole. could be but not always.
