I am a journeyman electrician. I just installed a 100 amp briggs and stratton transfer switch. Everything works fine (when power from utility is shut off, the generator starts, when power is turned on, the generator turns off) except: the power transfer from utility to standby power does not occur
Electrical Supplies - Briggs - & Stratton 100A Transfer Switch with Air Conditioning...
Hi and welcome to FixYa. I am Kelly a 35 + year electrician. Is this an automatic and GFI transfger switch?
Connections should be
N1 and N2 to Utility main T1 and T2 to house load E1 and E2 from Gen supply
Neutral lead must connect to all of the following in one circuit 1. the generator neutral 2. Main switch board neutral 3. the transfer switch neutral.
If this is a GFIC transfer switch you may have to disconnect the neutral from the generator. Local electrical codes are very restrictive and in many states disconnecting this neutral lead will result in your no longer being in compliance with existing code.
In the majority of transfer switches there is a "remote" and "no remote" setting that is explained in the transfer switch manual. It is related to terminals 178 and 183 of the transfer switch. You may have connected yours up in the "no remote" position.
One other comment is that if you have the sense line on the house load T1 and T2 Vs utility supply N1 and N2 it will perform exactly as you stated. It will work when the utility power goes off but will not switch from gen / standby power when the utility main power returns. If you routed T1 and T2 close to the N1 and N2 line sensor it can still via inductance cause the same problem even if you have it connected correctly. Make sure T1 and T2 are no where near the line sensor.
