Going from 30 amp to 50 amp
 

A general question about going from the 30 amp Hurricane up to a 50 amp: Do I need any extra equipment to plug it in at home? We have a 30 amp converter cable to connect it to household electricity.

If I understand your question fully, 30 and 50 Amp cable ends are different, so you'd need an adaptor to mate these. It sounds like you already have means (adaptor) to connect 30-Amp cable to house. Is that on 15- or 20-Amp receptacle?

If so I'd look at a 30-50 RV adaptor so you can also use it at campgrounds that may not have 50-Amp service.

Not sure what you mean by household electricity. My house has a 50-Amp in garage I installed to power a welder. With the right adaptor it could also power a large RV.

In most Class A MH's that have 50 amp service you can use a
30 amp service other than running the AC.

So by adding an adapter you can plug your 50 amp cable into a
30 amp service.

50AMP is a 220/240 VAC and 30AMP is 115/120 VAC.
That stated if you have upgraded your MH then a 50 to 30 adapter will only provide 30AMPs to one half of the circuits in the MH.
30 to 50 adapters are usually used for MH's that arrive at parks with only 50AMP receptacles.

Chance - usually a welder receptacle is 3 wire 240 volt, not suitable for an RV. RV 50 amp is 4 wire with both neutral and ground. 2- 50 amp 120 volt hot legs. (240 between the "hots" (30 amp RV is 3 wire 120 volt) I don't believe there is an adapter to use welder receptacle to power an RV..

Dutchman28- A 30 to 50 amp adapter has an internal jumper and powers both legs of a 50 amp service but still only provides 30 amps. power has to be monitored to avoid overload.
