Shore Power Adapters
Newmar Corporation does not recommend use of adapter, cheater, or dog-bone style connectors that will
modify the existing shore power cord to a different style of outlet. Use of this type of adapter will greatly
reduce the amount of available current in the unit, as well as create the potential for electrical failure and/or
fire.
If an adapter is used, there are
three common sizes of power cord adapters available to adjust to a
smaller amperage
outlet:
1. 30 amp to 20 amp
2. 50 amp to 20 amp
3. 50 amp to 30 amp
It is important to understand the risks involved and the possible effects of using adapters in conjunction with your coach.
Some of these risks and possible effects include:
• Melted or damaged adapters causing poor connection (or no connection at all)
• Melted or damaged 30 or 50 Amp plugs causing fluctuations in voltage that may damage electronics
• Insufficient amperage causing the tripping of a breaker at the post or a limited use of appliances
Low voltage can also be caused by use of adapters, long extension cords, or extension cords with an insufficient
wire size.
Newmar Corporation cannot assume liability for failures occurring to the RV, its electrical system, or any of its
components from the use of any electrical adapter.
