Voltec Power Cord Adapter, 50 Amp Plug And 30 Amp Receptacle, 18"

The Voltec 16-00571 power cord adapter converts a 50 amp 14-50 outlet into a 30 amp TT-30 RV receptacle using an 18 inch dogbone cord. A 50 amp male plug on one end and a 30 amp female connector on the other make it one of the most common adapters for 30 amp travel trailers and motorhomes.

When a site only offers 50 amp service, this adapter lets a 30 amp coach plug in and operate normally within its 30 amp limits.
