![]() These aren't as common as interlocks or solid-neutral switches, but are made by Eaton (CHGENxxxxxSN models) and Reliance Controls (their Panel/Link X-series - the regular Panel/Link units have a solid neutral), and combine a special switching neutral transfer interlock with panel spaces for standby loads. This situation of dueling neutral-ground bonds leads to objectionable stray current on grounding wires and will trip the GFCI on a generator with full-panel GFCI protection, even.Īs a result, you'll have to jettison the interlock kit approach in favor of a switching neutral transfer switch or panel. Twelve-gauge wire suits 15- to 20-amp breakers 8. This type of wire is suitable for start loads of 40-amps and a constant load of 35-amps. You could also plug it into a 15 or 20 amp breaker, but you run the risk of damaging your RV if you utilize more than the ranked power the circuit/outlet has been designed for. 30-amp circuit breakers, commonly used for a large boiler tank, require a 10-2 non-metallic or MC cable. A 30 amp Recreational Vehicle plug must actually be used with a 30 amp breaker. Water heaters and dryers are best served with 30 amps. Also, consider your breaker size for water heater. If you were to try to use such a generator with an interlock kit or solid neutral transfer switch, you'd cause untold mayhem due to the fact you just put your generator's neutral-ground bond in parallel with your house's. Wiring a breaker box is a highly technical skillknowing how it operates isn't. ![]() This is because generators meant for portable use (especially contractor/industrial grade generators) often have a bonded neutral, and some have GFCI protection on their 30 and 50A receptacles as well. However, if you want to use your generator as both a standby generator and as a portable power source, you'll need to be careful when setting up your standby power system. Don't let your generator hopes get neutral-ized! Many (most?) portable generators with a high enough wattage rating to support a 50A (14-50R or CS6365) receptacle also have a 30A (L14-30R) receptacle that can be used instead, so I would fit a 30A inlet box to your house if I were in your shoes. However, this wire size only covers 80 of the NEC requirement. Most generators that support 50A plugs also support 30A plugs as well The minimum wire size for a 30 AMP circuit is ten-gauge.
