Electrical problem or Transfer Switch problem?

[Buffchief]

I installed the Surge Guard surge protector last weekend. I installed it after the transfer switch. I can start the generator and get power to the RV. When I plug into shore power I get nothing. I don't hear the clunk of the transfer switch. I didn't remove the wires on the power in side of the transfer switch and the out wires are tight. Is there something I'm missing?

EMS should be installed on shore power in, and before the transfer switch.

Was the transfer switch already there? All you did was cut the 6/4 wire coming out of the transfer switch and then install the EMS?

Is there any error codes on the EMS display?

What happens if you turn the EMS off?

Here is my YouTube video on wiring a transfer switch. Perhaps something in there might help?

I swapped the generator leads and the shore power leads to the transfer switch. Power came on. Guess I have a bad transfer switch. Thanks for the help.

I have a 50amp GoPower transfer switch I just took out of my RV. PM me if you're interested. Link to device on Amazon.

Was in trailer for 3 months. (moved to Go Power IC2000)

The control board in the transfer switch needs to read around 105V or higher on L1 before the contactors will activate. Don't overlook the possibility that there might have been a problem at the power pedestal due to heavy air conditioner usage in the park. Also, make sure you don't have a disconnected wire to the control board.

When I had an issue with a Progressive Dynamics transfer switch earlier this year they told me to remove all power (shore power disconnected and generator off) then push on the top of the contactors. One of mine would not move indicating it had locked out and had to be replaced.

The Progressive Industries system offers directions for installation on either side of the transfer switch. The owner decides which risk he/she is willing to accept...Shore power issue damaging the transfer switch vs a generator or transfer switch issue sending faulty power through the rig.
About the only risk to the transfer switch by having the EMS downstream would be damage from 220 volts being applied as shore power. The other protections provided by the EMS would still be valid plus the built-in generator output is checked.

That is exactly what happened to mine. Got a new one coming. I swapped the generator and shore power leads for a temp fix.
