Go Power TS-30, GP-TS & TS-50M Transfer Switch Diagrams

Go Power TS-30 (64403), GP-TS and TS-50M (70278) are automatic AC transfer switches for different RV electrical arrangements. Use the illustrated source-selection guides, exact manufacturer model ratings and linked product photos to identify the correct series before considering installation.

How the two power-source arrangements differ

A transfer switch selects between two AC supply sources. The diagrams below show the role of the inputs and the RV distribution panel. They are identification aids, not terminal wiring diagrams.

30A / 120V: TS-30 or GP-TS

120V shore or generator supplyInput source A
120V inverter outputInput source B
Automatic transfer switchSelects one compatible AC source
120V RV circuitsSelected circuits
The GP-TS includes additional prewired connections. Circuit selection and source priority depend on the installed configuration.

50A / 120–240V: TS-50M

50A two-leg shore / generatorInput source A
Approved alternate AC sourceInput source B
Automatic transfer switchSelects one compatible AC source
50A two-leg distributionSelected circuits
The TS-50M switches both hot legs. The alternate source must be evaluated for the actual RV loads and distribution layout.
Three-source setups: Shore power, generator and a separate inverter cannot all be switched by one two-input transfer switch. The manufacturer's TS-30 and TS-50 installation guides describe configurations using two switches where required.

Exact model comparison

The TS-30 is the hardwire version. The GP-TS adds a prewired inverter plug and a receptacle intended to power the converter when shore power is present, helping avoid an inverter-to-converter charging loop. The TS-50M serves two-leg 50A systems and has a metal enclosure and selectable generator delay.

Model / part no. Rated AC service Configuration Dimensions (L × W × H)
TS-30 / 64403 30 A; 120 V AC, one leg Hardwired two-input switch 9.65 × 7.28 × 4.75 in
GP-TS / GP-TS 30 A; 120 V AC, one leg Prewired transfer switch 9.65 × 7.28 × 4.75 in
TS-50M / 70278 50 A; 120/240 V AC, two legs Double-pole transfer switch 9.4 × 7 × 4.4 in

Key differences inside the units

TS-30: A 30A relay, source-selection controls and hardwired AC connections inside the enclosure. GP-TS: The same 30A electrical service class with an attached inverter connection and converter-only-when-shore-powered receptacle. TS-50M: A double-pole switching arrangement for two 120V legs, with the source terminal groups shown in the original factory drawing.

These switches provide source transfer and back-feed isolation as designed. They should not be described as solar-to-battery transfer devices or treated as surge-protection units without an exact manufacturer specification.

Already using an inverter with an internal transfer switch?

Go Power's ASW-3000-12-TS (83829) 3,000W inverter includes its own 30A transfer function. It is shown as a different system choice, not as a replacement ATS and not as a guaranteed fit for an existing installation.

Original manufacturer drawings and service manuals

The Go Power manuals include the real relay and terminal drawings. Use these documents with the model label and current instructions; the simplified illustrations above intentionally omit electrical terminals and conductor routing.

Before ordering or working on AC wiring: Confirm the installed model, amperage, supply voltage, inverter output, distribution-panel configuration and approved cable arrangements. Disconnect shore power, generator and inverter/battery sources as applicable. Qualified RV electrical personnel should perform installation and service using the exact unit's factory instructions.
