Recommended Replacement For A Power Switch 50 Amp Transfer Switch
Updated 12/12/2025 | Published 12/19/2024
Question:
Hi, my 2000 Holiday Rambler Imperial motor coach has a Todd engineering ps250 power switch that has given up the ghost. The control board shorted out as a result of getting wet. Can the F50ATS replace this part directly? I am in Mexico and need the part urgently as I live in my motorhome. Thanks for your prompt reply

Hi Dell,
Yes, the Furrion Automatic Transfer Switch # F50ATS can replace your PS250 50 amp transfer switch. When swapping over to the unit transfer switch you'll want to first disconnect from shore or generator power. The shore power and generator terminals inside of the Furrion # F50ATS are flip flopped from how your PS250 is laid out but the concept is still the same between the two with the shore power terminal being the priority for the transfer switch to kick over to when available.
The red terminal will be your 1st power leg and the black will be the second power leg. The white terminal is for your neutral wire and the there's a bus bar mounted to the side of the box for your ground wires to run to. I usually wrap a small piece of painters tape around the jacketed portion of the wire and write what it's for in permanent marker on the tape so it's labeled and there can be no confusion later on.
If you get stuck or have anymore questions just let me know and I'd be happy to help.
