Why does my transfer switch keep burning up?

The problems come from the coils in the transfer switch itself. They need about 200 Vac to operate, and when the upper coil is only receiving say 100 volts, or maybe 150 or so in a brown out, they just sit there and cook because they aren’t meant to be energized for more than a split second during a transfer.

What to do if your Generac transfer switch Burns?

Generac sells a kit they call a “Brownout kit”, it is a voltage monitor/relay that wires into the transfer switch to help protect the switch. We replace the complete transfer mechanism, fuse block, transfer relay, and re-wire the damaged wires.

How does the transfer switch on a generator work?

Basically the older generators just have a utility sensing transformer that is sort of ‘dumb’ inside, and any voltage applied is passed onto the utility sensing section of the PCB in the generator. It sees that voltage and starts the shutdown sequence which involves removing the 23 wire from ground and moving the transfer switch back to utility.

What happens when a transfer switch goes bad?

The same can happen even if voltage is good and the little limit switch has gone bad. Those little switches disconnect power from the coil as soon as the transfer in one direction takes place. If the power is left on to the coil (in either position) they will burn out as well.

Can a reliance pro / Tran transfer switch burn out?

This is acceptable for peak wattage but not recommended for running wattage. Pulling more than the rated wattage through the Reliance Pro/Tran ® transfer switch could burn out the neutral wire, overheat the main wiring in the transfer switch and cause a fire.

How many amps are in a reliance pro transfer switch?

Yes. The switches and wires in each transfer switch are rated for 20 amps. However, in the generator mode, each circuit is limited to the amperage of the circuit breakers in the Reliance Pro/Tran transfer switch.
