RV Generator Power Extension Cords

Use at least 10 AWG copper for a 30A TT-30 or L5-30 run and 6 AWG for a 50A 14-50 or SS2-50 run, stepping up one gauge for very long lengths to limit voltage drop. An undersized cord overheats and reduces appliance performance; the cord should match or exceed the RV inlet and generator outlet rating.

An extension cord carries the same NEMA configuration at both ends (male plug to matching female receptacle) simply to extend reach from generator to RV. An adapter cord set, or dogbone, changes one NEMA configuration into another, such as an L14-30 generator outlet to a TT-30 RV inlet, when the two connectors do not match.

Yes, provided the generator, cord and RV service all support the load. A 30A TT-30 circuit supplies about 3,750 W at 125 V, enough for one roof air conditioner with limited other loads, while a 50A 125/250V service supplies up to 12,500 W for multiple air conditioners. Match total running and startup watts to the circuit and use the correct gauge cord.

Yes. They are UL/cUL and ETL listed, use RoHS/REACH/PAHS compliant cable with weather-resistant jackets and molded strain relief, and can be made in custom lengths, colors and connector combinations with optional locking rings. MOQ is 200-1000 pieces, samples in 7-15 days and lead time 15-20 working days.
