Hi,

[size=2]Just wanted to throw this your way in case you want to build one as they’re getting scarce.

[/size] [FONT=&quot]The stove always has power as it’s the main load you want running in the miser switch. When you turn your stove on; it could be one element, fan, coffee pot connected to the outlet attached to it, the current sensing relays will detect and open the power relay feeding the dryer. When this happens, the dryer’s power is cut off. When the stove load is reduced to just under your preset level of 1-100 Amps (in this case 10Amps (40 (stove)-30 (dryer)=10Amps) it will allow the power relay to close and the dryer will work at the same time as the stove. So anything over 10 Amps on either line running through the current sensor and the dryer will not work disallowing the circuit to exceed 40 Amps.

  • [FONT=&quot]You can adjust the current sensors from 1-100 Amps, even independently. Most stoves have an outlet (coffee pot connected), lights or fan. If any draw is detected above your preset level it will stop the dryer from working. [/FONT]
  • [FONT=&quot]You can install this miser switch into the main lines after a main 60 or 100 Amp disconnect and control many appliances through prioritization. [/FONT]
  • [FONT=&quot]It can control relays or contactors up to the rating of you service entrance, not limited to 40 Amps and two loads like with the old miser switches.[/FONT]
  • [FONT=&quot]You can run individual sensor wires from appliances to have control over your power relays with a smaller relay.[/FONT]
