KW Usage for Horse Take

What you have is a watt hour meter. You can find out everything you need by clicking.

That meter is 240 V with a neutral ( the neutral is connected to ground inside the dwelling) the two power leads go the fuse/circuit breaker panel. If in the dwelling you some how only used 120v on one leg of the incoming power the meter would of course still read the KW properly. So I do not see a problem with reading watts into a heater. Of course you could posibly split the heater elements int two different 120 v legs and then balance thru the meter

New electric meters for the most part would not register any kWh unless you have a 240 supply to them. The load can be 120 as long as the supply is 240. With a meter that old, it should work just fine on 120 volts only and will probably be as accurate as you would need. Calibration might be off slightly but the difference won't be much. As was mentioned earlier in another posting, this meter measures kWh. It reads kWh, not amps.

Thanks, I have the info I needed. Happy Holidays

I am assuming that you are in North America and have 240 V, 3 wire service. (240VAC in Europe and European meters are different animals). If the meter is rated for 240V it means that it has a 240V potential coil and this coil must be wired to 240V for the meter to be at all accurate. If this is the case, than loading either 120 V leg will give you an accurate reading of Watt-Hours. If you only have 120V service than you need to find a meter with a 120V potential coil.
