Im doing a interlock with an inlet for a customer
The generator they are purchasing has a 30 amp 240v twist loc configuration .So do I size my rx
Wire to 30 amps or 8000 watts ?
Be careful when hooking up RVs (campers) with 30 Amp twist locks.
No RV with 8000 watt generator, come with 30 Amp Mains. RVs that come with over 4000 W generator are equipped with 50 Amp 4-wire twistlocks.
Besides, for a generator this size, it would be too big to be considered portable- - -it would be a monster to haul around on wheels. Even though the plugs are rated 240 volts-- no 240- volt plug is present inside the RV itself. All devices/appliances run on 120-volt. The panel has split bus to feed the branch circuits using each separate phase to provide 120 volts. No 240 branch except the main CB. European tour buses do come with 220 volts for cooking for riders' meals. I'm sure you've seen those Volvos and MBs.
I'll be in Hungary and Germany [soon] so I'll be riding in one of these buses. :happyyes:
Don't be confused with the 30 Amp 240 volts twistlocks that are sometimes used for household dryers.
This 30 Amp RV plug is stamped for 125 volt RV use. (NEMA L5 30 P 125 V). Some of these plugs are also used in data centers and X-ray machines.
Seasoned electricians without RV experience got “burned” by RV owners when they hook up this L5 30 P plugs to a 240 volt power source.
Take care.
