Had to replace Automatic Transfer Switch

Our 30 amp transfer switch failed while we were dry camping recently so were unable to get power from our Onan generator. Used the chassis engine as a backup source, not a problem.
When we got back I popped the lid on the switch, an Iota ITS-30RL, and probed it with my DMM. The generator voltage was present on the input but not the output. The control board LED was off indicating the control board had failed.

Neither the switch nor the control board is available any longer so a different brand was in order.

I decided to go with the Progressive Dynamics PD5110010Q. This switch has the hot and neutral connections encapsulated within flip connectors. I had some difficulty jamming the stranded wires of the AC line in the connector. I taped all the connectors with electrical tape to insure that the flip levers don’t flop around.

I like that the connections are fully encapsulated (grounds still connect to a bus bar). I also like that the connections are not rigid like on a bus bar and are free to flex.



All comments IMO.
  • I'm not a fan of the flip connectors. The transfer switch I bought looks very similar, but had a Furrion brand logo on it.

    The main difference I see is the instructions had me connect directly to the terminals on the contactor itself. I used crimped ring terminals.





    I use mine in an unconventional fashion: http://2manytoyz.com/autoxfersw.html

    If you're okay with those connectors, great. If not, it's easy enough to use ring terminals instead, and you won't need tape.

    That is a clean looking install. Your input, gen, and output are all stranded copper wire.

    Ours has stranded copper only for the AC line. Gen and output are solid copper wire. I'm satisfied with the flip connectors. They will go where the solid wires best fit with their more limited mobility. The flip connectors are spring loaded so they likely didn't need to be taped but their was little information available so overkill is in order.
