Transfer Switch

Recommended Posts

With the Progressive switch, you are using the relays whether you are on the generator or the shore power.


My Progressive switch is several years old. My Esco switch is 7 years old.


If you burned one out in one year, you probably need to do some more investigation of your electrical system beyond just replacing the transfer switch.

Here's an update.....

Last night I changed the generator input line plug, L-30 14 to the normal 30 amp RV plug and had limited power thru the transfer switch. This morning I removed the transfer switch and spliced the shore power input cable to the cable going to the main breaker panel. The Progressive industries 50amp EMC showed it was passing power thru but it wasn't reaching the panel. Time to remove the breaker panel cover and start probing there. After some careful wire probing and meter reading, I discovered that the main 50 amp dual breaker was only passing current on only 1 side, leaving the other side dead. Change the breaker, and all is good.

Never had a main breaker go bad, but it is. By the way its a Square D brand. Maybe made in China.

On the upside, I need to give kudo's to the Progressive Industries team. Last night when I called the after hours line I evidently got the owner. He didn't say so, but today on a return call, David the tech I spoke with informed me of that. Everyone was very helpful and David put me on the path to checking breakers which let me find the bad main.

Now back to our normal week events....
