GE electromechanical demand meters

[SeniorElectricalEngineer]

Greetings everyone,

Last week I was surveying an electrical room and noticed an older GE demand meter referenced in the attached photo. Could you figure out what the max. demand value this meter indicates?

It's either 0.34 kw or (2400 x 0.34) 816 kw. I would guess the latter. Big service?

Looks like about 0.34 x 2400 or 816 kW. Does it seem reasonable? But remember, this is just the maximum since the last time it was reset.

816 kW appears to be the correct value. Take a look at the single line diagram.
