Dumb question alert. Can I use 15 amp power?

I have been using this setup for several years now with two trailers plugged into the garage here at CAMP BACKYARD. One trailer is plugged into a 15AMP garage 120VAC circuit and the other tralier is plugged into a dedicated 20AMP garage 120VAC circuit. Both trailer run everything in side including the 13,500 BTU air conditioners. Just have to watch what else is running at the same time otherwise it will trip the garage circuit breaker.

I use the RV30A-15A long adapter from WALMART that looks like this...

I cannot use the small round black small adapters that look like this as they will overheat on me after being used just for a short period of time


I also use a good HD Contractor type 10-3 50-foot extension cord plugged into the the garage 120VAC 15/20AMP receptacle. The contractor grade 10-3 HD extension cords are expensive - I found mine at a yard sale... My RV30A-15A adapter is then plugged into the end of this HD extension cord and then the trailer 30A Shore Power Cable is plugged into the adapter laying in the middle of the backyard. I have also used a 12-3 HD 50-foot extension as well without problems. You cannot use the red/orange 14-3/16-3 cheap extension cords you find at WALMART. They are too small to use. You also should make sure all three conductors are used. The HD extension cord looks like this


I like to use a RV 120VAC PLUG-IN AC VOLTMETER inside the trailer Plugged in where I can get a quick glance at it before turning on the Air Conditioner. It looks like this

This has a great feature with its SAFE ZONE marked in "GREEN". If the reading is outside this safe zone the air conditioner will most likey NOT WORK.

I always watch my RV120VAC Voltmeter just prior to turning on my Air Conditioner to make sure it is reading in the "GREEN" zone. I also on occasion feel my connections in the garage and laying out on the ground to make sure they are not warm to touch indicating poor connections.

Use a good HEAVY DUTY 10-gauge or 12-gauge Extension Cord and you should be good to go... Don't think you can get away with the cheap 14-16 gauge extension cord - they will get hot on you and may burn up your air conditioner due to power drop. Not worth it...

I also chuckle at some of the questions posted and perhaps you should re-read your original question. You posted nothing about wanting to join friends; you posted 'first time' and this is only one of your many posts on the subject. You received some very good advice from some very knowledgeable members and then post 'I have to chuckle.....'. As new as you appear to be to the world of RV'ing, you should stop with the childish attitude of "oh boy, I'm going camping" and take your RV out for a mature evaluation how it works and your responsibilities on the road.
