Thanks. I replaced the outlet only to find that wasn't the issue. Apparently air conditioner unit 2 now trips the breaker whenever you hard power cycle it. Must be a transient surge. Can't remotely hard cycle it anymore, so I hope it works without cycling.</div>

Hi Marc, Brian,</div>
<div style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
One of the 20A power receptacles that we use to cycling the air conditioners malfunctioned during the night and we lost power to AC2. Of course these are the remote controlled receptacles we borrowed from your group. When we plug the receptacle in, it trips
the breaker within a few seconds. I noticed you installed a similar unit for cycling the power on the controls. Do you happen to have another one on hand we could use to replace it?</div>
<div style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Ellen, it looks pretty simple to swap one of these out, but if I run into issues, are you around today for trouble shooting?</div>
<div style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Thanks,</div>
