SmarPlug Systems, which makes showerpower cords, has launched a service program to make sure its equipment isn’t leaking stray current. The company’s 16-, 30-, 32- and 50-amp inlets and connectors can be serviced or upgraded to current technology.

All the parts kits are compatible with all previous generation products. Offered for each of the four amperages, the kids include a Female Connector Service Kit, a Gasket Service Kit and a Male Inlet Connector Service kit.

“Offering service kits is an easy and inexpensive way for a boat or RV owner to bring new life to their shorepower equipment,” said Tony Barber, SmartPlug Systems CEO, in a statement.

With double sidelocking clips and an asymmetrical shape, SmartPlug can only be connected in the correct position.
