The Ground Fault Interrupter (GFI) 15 amp plug on the end of the Tesla Roadster OEM 120 VAC charge cable has single handedly been responsible for more bricked Roadsters (let the battery go dead) events than any other Roadster accessory.

The plug is rated for 15 Amps, and a charging Roadster uses all 15 Amps during charge.

The outlets they are plugged into are typically daisy chained, not dedicated outlets, and the reduced current available either blows a circuit breaker, or more insidiously, often heats up the plug, eventually compromising the low tech internal circuitry sensing ground fault.

They also do not fail conclusively, often limping along once compromised, providing substandard charging, and in worst case scenarios, failing completely while you have the car in storage, or on vacation.

With Roadsters in our Service Center, we routinely replace this failure prone component, and have never found one without internal circuit board discoloration from excessive heat, ready to fail when you least expect it.

Replacement is straight forward, requiring only a #2 Phillips Screw Driver.

This replacement is cheap insurance.
