The Go Power! TS-50M is a 50 amp, double-pole automatic transfer switch in a metal enclosure, rated for 120/240 VAC. It's made for RVs with 50 amp service and two 120 volt legs. When shore or generator power is available it connects that source to your breaker panel, and when you unplug it switches your inverter output in.
The switch chooses between two separate AC sources, and each source can bring two 120 volt, 50 amp inputs or a single 120 volt, 50 amp input. Sources can be power cords, generators or onboard inverters. Go Power pairs it with Go Power! inverters that don't have a built-in transfer switch.
Three sets of lugs, labeled POWERCORD, GENERATOR and PANEL, each take a HOT 1 (black), HOT 2 (red) and neutral (white) conductor. On 240 volt wiring, it doesn't matter which hot goes to HOT 1 and which goes to HOT 2.
The generator is the dominant source. A preprogrammed 20 to 30 second delay gives the generator a brief warm-up before the switch hands it the load, and Go Power lists the transfer delay as selectable. An audible click tells you when the switch engages or disengages.
Go Power builds in mechanical and electrical safety interlocks to prevent AC back-feed when an inverter is part of the system.
The metal enclosure measures 9.4 x 7 x 4.4 inches and weighs 7 pounds. The lid snaps on, and a direct access hole through the enclosure reaches the ground bar.
50 amp RV with an inverter. Connect the inverter to the POWERCORD lugs as the default source and shore power or the generator to the GENERATOR lugs as the dominant source, so the inverter runs only when the others are off.
Power cord and generator. Put the power cord and generator on their own lug sets and let the switch move the panel to the generator once it has warmed up.
Designated inverter circuits. Install the TS-50M on the line side of the main panel and add a TS-30 between the inverter and a 30 amp branch circuit that feeds a designated circuit panel. The inverter then supplies only those circuits when 50 amp power is absent.
The TS-50M is the double-pole, 120/240 volt switch for 50 amp service. For a 30 amp RV, Go Power points to the TS-30 instead. The two can also work together in a hybrid system, with the TS-30 handling a 30 amp branch of designated inverter circuits.
To run the whole panel from a 120 volt inverter, land the inverter hot on HOT 1 and add a jumper of the same gauge from HOT 1 to HOT 2 on the input side. The entire load then runs at 120 volts, and 240 volt loads won't run from the inverter. Isolate any load you don't want on inverter power. The manual notes the switch is sometimes used as a lock-out, for example to keep a battery charger or air conditioner off the inverter while it still runs from shore or generator power.
Mount it with screws through the holes in the bottom corners, on an interior surface out of direct weather that stays accessible, ideally near the power cord entry or generator output. Run an 8 gauge chassis ground to the ground bar and tighten ground terminals to at least 20 inch-pounds. Never install it in a battery compartment or anywhere flammable liquids are stored.
No. A 120 volt inverter feeding both legs can only run 120 volt loads. 240 volt loads run when shore or generator power supplies both legs.
On arrangements with three power supplies, the generator is selected first when the power cord, generator and inverter are all on. Shut it down and the switch moves to the power cord, and when you unplug it moves to the inverter.
Go Power lists a 2-year warranty for the TS-50M.
The Go Power! 50 Amp Automatic Transfer Switch moves both legs of your RV panel between shore power, a generator and your inverter on its own, with generator priority and back-feed interlocks. If you'd like help planning the wiring, the Outbound Power team is happy to help.
