Re: [A/S] Electrical: (Was.. 220 volt surge)

["Dr. Gerald N. Johnson, electrical engineer" <geraldj@xxxxxxxx>]

Campgrounds are more likely 20 amp with a few 30 and 50 sprinkled about
than mostly 30 and 50. The National Electrical Code (which many don't
meet) requires all to have 20 amp, 70% to have both 20 and 30 and 5% to
have 20, 30, and 50. 15 and 20 amp 120 volt receptacles are required to
have ground fault protection. In older campgrounds the outlet may be 20
but the power may not be there for more than 3 to 5 amps. And in some
gatherings with temporary power 3 amps is the limit.
