Few lights: 2 - 4

With just these few items running I am at or slightly above 30 amps already. That coupled with voltage drop down to 112 - 115 put me over. Guess certain pedestal breakers can handle the overload for a little longer than this one did. Will need to make sure that I run my water heater on Gas if AC is running. Does not take long to hit 30 amps!
The lower the voltage the higher the amps. More amps = more heat in the breaker. It's a voltage issue I'm sure. Shut the electric water heater off at night. That is what we do. We only turn on the water heater when we need it.

yup, to the OP: we have tripped the 30A breaker at the post as you did when running AC, hot water, fridge, lights, etc. on electric. What will happen is everything will be working fine until that moment in time when electric HW and fridge happen to be working at the same time and it tips it over the limit. So if AC is blasting and someone wants to use microwave I will usually just turn off the HW or switch fridge over to gas for the few minutes that's in use.

There are also plenty of other small stuff that you might not even consider in your calculation that adds up: phones/computers charging, TV or stereo on, etc etc.

Something I discovered this summer is that mosquito spray can set of your LP alarm!! LOL. The DW was standing outside the screen door spraying herself down and the LP alarm went nuts. First time we had ever really heard it, so it was nice to know that it works!

On 50 amp I run everything on electric at the same time and never had a problem. 2 a/c's, water heater, microwave, tv set, coffee pot, refrigerator. Again - Everything.

Thanks to all who provided their feedback. I will watch my usage on my next trip and see if things get better. It appears that I was using too many items at the same time coupled with a drop in voltage. As for the LP/CO detector hope that was a one time thing. I will carry my 30 to 50 dog bone as well and will change over if 50 amp is available and 30 amp is giving me issues.

Just to throw this out. When all this is happening grab on to the plug at the post and the last foot of wire. Is it warm to the touch? If so look at the plug, if it looks like the plastic is deformed put on a new end... the kind that screws on direct to the wires. If you have had to use the 30A rv to 15A dogbone often enough they create lots of heat due to current draw.

I saw no mention of the refrigerator. Was it on and running on electric also maybe. Might be something you forgot to factor into your considerations. After all, cold beer is more important than hot water. Or at least that's what I've been told.

My extension cord (30amp) was very hot so I cleaned off the prongs and tried to clean the outlet. That really did not help so I just used the camper cord with basically the same result. I think the outlet was loose as the cord got extremelly hot.

The fridge was running so that is about 5 amps.

I think your AC is pulling to much power. On startup your numbers sounds about right. But once it is up and going I thought mine settled down to 5-8 amps. But this is from 2 year old memory when I check my power draw. If I had good power supply at my new place I would go out and check.

I've had this happen many times on hot days when the hot water heater kicks in while the AC is running on both my old and new TT when I'm hooked up to a 30 amp service. I also solve this by putting the hot water on propane. At other times I've had no problems at all. It seems to be related to how much power is being used by the whole RV park and the corresponding voltage drop. It seems to happen more at older parks rather than new parks that have better power hookups.
