We pay a charge based on peak demand.

My concern about insisting on a demand meter for the tanning salon is that the first 50 kva demand is free. The tenant would insist that their first 50 kva is non-peak and is therefore free. I think 50 kva is about 140 amps at 208 volt, 3 phase. They have a 200 amp feeder.

The landlord has been reading the other tenant's demand meter but when I look at his records, one number is always 160. Maybe it's the peak demand that hasn't been reset and he probably isn't charging for demand.

The demand meter is a Schlumbeger Vectron. It has a multiplier of 1 but since it's connected to ct's I don't know what that means.
