240 to120V adapter

I thought I replied to this but don't see my post.

Anyway, I have a cordset that came with a portable generator that plugs into the 14-30 receptacle and has some sort of molded in GFCI/overcurrent protection device on four individual 5-15 cord connectors.
 
Whats the application? If on a jobsite I would probably want a cable 14-50P to 50 amp CS twistlock female and a spider box. If for my own personal use in a controlled environment then there are *ahem* other options.

If for indoors, CEP makes some smaller lunchbox style boxes that still have OSHA compliant GFCI modules.

Ahhh ok, I was thinking about much different use scenarios. OMG that thing is expensive, but I guess its still cheaper than having the receptacle changed out.

There are cheaper versions, but going back to the OP I don't believe that any of them have built in GFCI protection. There is an internal non-replaceable fuse to protect items expecting to go into a 15A circuit.

I use one of these in my own kitchen. I have a 50A range circuit and a gas line, and the gas range is plugged into an adapter in the range circuit.

Yikes, why did I remember GFCI but forget about overcurrent protection! :dunce: The application here is electric car charging. There are only 2 slots available in the service panel to install the NEMA 14-50R, but I want the option to trickle charge at 120V. Do people who use these for gas ranges and RV's not care about overcurrent and GFCI protection?
 
The adapters made for gas ranges have fuses built in. Dunno about the ones made for RVs.

You can use a 'spider box', which takes a 120/240V 50A input and provides a bunch of receptacles with over current and gfci protection; probably a useful jobsite tool.

However this thread appears to be about to morph into a DIY thread. Don't go there; have an electrician install both the 14-50R and the 5-15R and be done with it.
