Question Help me not start a fire, pls

[sjohn05]

I have a new to me camper that I'm trying to plug in for the first time. The surge protector I ordered didn't match up to the cord that came with the camper. Since I'm using a 30amp to 15amp adapter to plug into my garage and only intend to run the AC on low, would this be safe to plug in? I have the breakers off to everything but the AC.

Thanks!

I would suggest you check the owner's manual for your particular AC unit. They usually draw at least 15 amps to run but a huge surge will take place during start up. I see you are using a fairly long extension cord. The shorter the cord the better plus......is that cord rated for 15 amps? Note the size of the cable your adapter uses. If it is underrated it will overheat and could cause a fire. Better to be safe than sorry. Can you connect to 30 amp without your surge protector? If you are using a "known" power source, you could get away without using it.

15amp is a bit light to run an AC on. If it is a smaller AC (13k BTU) you may be able to get away with it, but the cord needs to be heavy duty otherwise it may overheat.

You will find out if/when the breaker pops as it will only be rated for 15amp and the spike from the AC starting may pop it. Especially if anything else is running in that circuit. I don’t see the risk to the RV….but mainly to the cord.

If you plan on doing this frequently, you should have a 30amp RV outlet installed…that way you can feel confident in running what you want.
