30 amp information

I am rebuilding a 1985 Sunline. I do not understand about the 30amp cord, and long an extention cord I can use. Does the thirty amp run all the stuff in my trailer?

30 amps is the rating of the cable. I have the same in my 87 T1661. It runs to the circuit breaker box / fuse box inside the camper. I've had mine hooked to a 200 ft industrial strength extension chord a few times already and had no problems. Of course I had to get the 30 amp /120 adapter for the end of the cable. I've ran the air conditioner, a bunch of lights, everything worked fine. Just need to be sure the extension chord can handle the load. There's a rating tag on the chords that should tell the maximum load capacity.

If you have a 12 volt inverter that's hooked up inside your camper, the chances are your system is like mine and will operate off battery power or off the direct electric connection.

Good luck!

I hope this helps!

Most campgrounds offer 50 amp, 30 amp and 20 amp service - necessary for todays RV'rs power needs (AC, Microwave, Electric Hot Water, Sat. etc.) If you are a heavy power user, always opt for the 30 amp service. The 30 amp to 20 amp adapter (available at RV Supply Companies) cannot handle heavy loads (overheats the connection point - trips the campground breaker.) 30 amp extension cords are also available at most RV supply stores in varying lengths. I installed an exterior 30 amp receptacle at home near my camper parking spot.

If you don't have an AC or many 110/120 appliances you should be ok with 20 amp service (using the adapter.) The interior lights, range fan, bath exhaust fan are 12 Volt components supplied by the 110/120 to 12 Volt Power Converter or on board external battery.

Just a small note: The 30 amp cord and any extensions should be #10 size wire.
