Any electricians out there. Need help getting 480VAC (3 phase) to look like 240vac single phase.
The power company here will install a small unit that monitors your AC (208 unit and 240 unit, assume single phase) line and certain times (emergencies) flip off your AC to the air conditioner for 15 minutes with a credit each month.
They said it will only work on 208 or 240vac and we have a 480vac 3 phase AC units. If I can get it to 240 and show them the thermostat wires they will install it for me.
At first I was thinking about a 2:1 step down transformer. They signal the box, so not sure if a transformer will screw the signalling up.
Not sure what power it pulls but I assume from run from my (240vac) power.
Could a couple same sized resistor in series to make a voltage divider work for this. It will be installed by an electrician.
Any other ideas?
