[font=Comic Sans Ms]Hi everyone! I just talked my husband into buying a popup tent. We're brand spanking new to camping but I think my two girls will love it. Can anyone tell me what's the difference between 50amps vs 30amps (besides 20amps biggrin.gif )? Which is better any why?

One note of caution. Consumer and standard Commercial grade electrical equipment (receptacles, breakers, plugs etc.) are manufactured to a basic standard of 80% contiuous use of the rating. That is, a 30 amp receptacle and plug are built to continually allow 80% of 30 amps, or 24 amps, continuously without building up excess heat, breaking down insulation, burning contact points etc. These items can run 100%, or 30 amp, for a short period of time.

Are continuous duty rated receptacles, plugs etc. available. Yes. At a cost. A 20 amp duplex receptacle, like in home, standard grade, costs $2.37 at Lowes. The higher grade receptacle costs $24.14.

Another example is the service equipment coming from the electric company. It, too, is rated at 80% continuous duty. A 200 amp service is designed to provide 160 amps continuously, a 400 amp service-320 amps cont. etc.

Exceed this, and trailer plugs melt and burn. Receptacles do the same thing. Cords breakdown over time. It may not an instantaneous occurrence, but overheating electrical equipment over time slowly breaks it down as well. If you want 100% continuous duty, EVERYTHING must be within that specification.
