Instructions for AC Wiring(ISW Inverter 200-400)



The cables linking the GP-ISW to the appliances are the AC cables. The following points must be observed for the AC Wiring



 • Review the safety information at the start of this manual before completing any AC wire installation steps.

• All AC Wiring must be approved for the application (RV, Marine, Residential). For RV applications, this may be solid wire in multi-conductor cables, but stranded wire is required if single conductors are used.

• All wiring must be rated to 75°C or higher.

• Do not connect the AC Output to an AC Power source (generator / shore power). Severe damage may occur and will not be covered under the warranty.

• Always use properly rated circuit breakers / fuses.

• Make sure all cables have a smooth bend radius and no kinks are present.


AC Output Interface


Socket Type (F)

North America (GFCI)


GFCI (Ground Fault Circuit Interruption) Outlets


Compliance with UL standards requires that Go Power! test and recommend specific GFCIs for use on the AC output of the GP-ISW. GFCIs shall be installed in the AC output wiring system to protect all branch circuits.


A GFCI is a device that de–energizes a circuit when a current exceeds a specified value that is less than that required to open the circuit breaker. GFCIs are intended to protect people from electric shocks and are usually required in wet or damp locations.


The table below lists GFCIs that have been tested and will function properly when connected to the AC output of the GP-ISW.

Manufacturer Model Number
Cooper Wiring Devices Type VGF20 Rated 125V, 20A
Leviton Mfg Co Inc Type 7899-W, Rated 125V, 20A
Hubbell Inc Wiring Device Dev Type GF20, Rated 125V, 20A


Connecting the AC Loads


Calculate the total power consumption of the output load. Make sure that the total power consumption does not exceed the rated power. If the total power consumption is higher than the rated power of the inverter, remove the non-critical loads until the total power consumption is below the rated power.
