What a adapter does
An adapter changes one plug or receptacle style to another, for example a generator outlet to an RV or transfer-switch cord. Use only where the amperage and polarity match.
| Voltage | Maximum watts (amps × volts) | Plan for about 80% continuous |
|---|---|---|
| 120 V | 3,600 W | 2,880 W |
| 240 V | 7,200 W | 5,760 W |

A matching outlet is necessary but not sufficient: the generator's watts, the inlet, the cord and the panel all have to be correct. An electrician confirms the whole chain.
