RE: Pulling more than 50 amps ?

... If he stands by his assumption, that you cannot draw more than 50 amps on a 50 amp CG plug, the names stay. I would hope the OP asks this CG electrician to clarify what he told the OP. DougUh, the CG electrician didn't say you cannot draw more than 50 amps on a 50 amp plug. According to the OP: "Our park electrician says that some of the big rigs with 3 ACs and electric everything can sometimes draw more than 50A from a 50A pedestal." What am I missing? My thoughts also. I really got confused by the name calling over what seemed such a simple statement. My simplistic mind saw no confusion on the electrician’s statement. I read it as him implying that the “big rig” could draw more than 50 amps from one leg of the 50 amp service and trip that breaker.

RE: Pulling more than 50 amps ?

BTW, I would keep that Idiot away from my Campsite and RV. Doug Huh? You just agreed with him now he's an idiot? Yeah, that made no sense to me. The electrician is absolutely correct that a large all electric RV could possibly pull over 50 amps from either leg of the 50 amp park service and trip that 50 amp 240 vac two pole ganged breaker. (And it has to be a ganged breaker since it is a split phase system and has a common neutral.) An EMS might prevent it. I don’t know. But without an EMS there is nothing to limit the current flow but the circuit breaker itself. And perfectly balanced, the RV could pull 50 amps on both legs of the 50 amp service for a total of 100 amps and still not trip the park breaker unless manufacturing tolerance variations set the breaker trip point slightly below the breaker rating. And that would be minimal. Inversely, it could even be higher than the labeled rating due to those same tolerances. And you can talk about it in amps (pure current flow) or in watts (current times volts). Doesn’t matter. In the end it still comes down to the number of amps flowing thru the breaker that trips it.

RE: Tested your LP detector lately?

False alarm or end of life chirp? Mine started chirping just short of the expiration date on the detector. And I replaced it immediately.

RE: Low Voltage on One 50A Leg

Measured “unloaded” I would guess the campground power was low on that leg. Resistance can cause the voltage to be lower. But that would only occur if there as a load (current flow) thru that resistance. Did you try measuring voltage at the park pedestal receptacle?

RE: Pulling more than 50 amps ?

I would not be surprised at all if some of the large very high end MHs with 3 A/Cs and mostly all electric for everything else could easily pull over 100 amps and exceed the 240vac/50 amp park supply. 3 A/Cs, larger microwaves, induction cooktops, residential fridge, freezers, multiple TVs, high end home theater systems, washer/dryer, etc. along with all the other more common electrical features and that is a lot of power. I would believe the park electrician.

RE: "My Forums" link takes forever

Happens fairly often. Slow to non existent for a few days. Then back to normal for a while.

RE: Checking on Wheel Bearing Heat

I carry a temp gun, but rarely use it. I just use the touch method. The hubs on the shady side will always be what ever the ambient air temp is. But the sunny side hubs, tires, and wheels will always be considerably warmer, but not so hot I can't lay my hand on them. And I do have a TPMS.

RE: Electrical Problem, or no?

Neutral and ground should be bonded at the park main service panel. That means neutral and ground should essentially be the same and the voltage readings should be the same. You have a bad ground connection somewhere.

RE: Acceptable electrical load

Although RV's are classed as plug in devices and so exempt from the National Electric Code, it is best practise to follow using 80% as the maximum continuous load. For 15 amp service that is 12 amps For 20 amp service that is 16 amps For a 30 amp service that is 24 amps For a 50 amp service that is 30 amps per leg Try as best as you can to balance the two legs. Any imbalance is sent back via the Neutral wire. Actually 80% of 50 is 40 amps.

RE: Acceptable electrical load

Just make sure the A/C units are on different "legs" of the 240V feed. .......... Over simplifying. Balancing is a good idea. But before wiring in a 2nd A/C you need to look at how distribution is already done. If the existing A/C is on hot leg 1; and the water heater, microwave, converter, and that outlet used to operate the DW’s 1500 watt hair dryer are on hot leg 2, then hot leg 2 already far exceeds hot leg 1. Adding the 2nd A/C to hot leg 2 would compound the problem. In that case putting the 2nd A/C on hot leg 1 would make more sense. Or better, move some things from hot leg 2 to hot leg 1 before adding the 2nd A/C to hot leg 2. Two A/Cs are 30 running amps or less. That is only 60% of the full 50 amps available for one leg if no other high current device is also connected to that hot leg. Need to look at the big picture.

RE: Acceptable electrical load

All the electrical circuits are circuit breaker protected with the appropriate amp rating for the wiring to those circuits. And you have a main 50 amp circuit breaker for the incoming power. And, of course, there is the park power pedestal 50 amp breaker. If you exceed the amp rating of any of these that circuit breaker will trip before damage is done. If you add devices and it trips one of your circuit breakers then you will know that there is too much running off that breaker. The you can try another circuit. If your breaker panel has spare slots, you might add a new breaker and run new wires to new outlet(s). And the 50 amp park pedestal almost always has a standard 20 amp 120 vac outlet. Use that with a good extension cord to run the outdoor freezer.

RE: Problem with 50 amp cord

If as you say the cord is an "extension" cord which is attached to your existing 50A cord you are running as a guess close to 50' of cord between the RV and the outlet. I don't know what the reliability of the post is, but you might have a serious Amperage drop due to the cords length which is affecting the appliance. 25’ power cord plus 25’ extension of 8 ga wire equals 50’ of cord running 50 amps equals voltage drop of about 4 volts. 120 vac source minus 4 volts equals 116 operating voltage. Not a problem.

RE: Problem with 50 amp cord

From your description it does sound like the extension cord. Sounds like either a broken wire or a bad wire connection in one of the connector ends. If no visible damage then likely a manufacturing defect. If it has molded connectors on each end, then the only repair option is to cut those off and replace with new connectors.

I never resize a picture before posting. When inserting a picture I just put in 550 for the width and it always works fine.

RE: Urgent need help

Not sure a failure at a campground like that is covered by roadside assistance. A call would verify it one way or another. Have you contacted Starcraft directly rather than calling the dealer? That is the first place to start to get the ball rolling toward making good on the repairs.

RE: Cracker Barrel

I suggest using google maps satellite view before pulling into a CB. Most do have RV spots. But some are easy in/easy out. Some are not so easy access even though they have the spots available. And all too often, if the place is crowded at the time there will likely be cars in the RV spots. Of course the sat view does not tell you what is there parked there at the time, but will give you an idea of what to expect on entering and exiting.

RE: Excessive Heat in Fifth Wheel

Our 5er does better than that. Also being in Texas we have been out in temps over 100 degrees and, for the most part, once the trailer is cooled the rear 15K A/C will keep it cool except for maybe the hottest part of the day. I would guess either the A/C is not cooling properly or the trailer insulation is not adequate.

RE: Exclusive: Utterly Unique Fifth Wheel

Interesting concept. With the high ceilings a ceiling fan would help circulate the air. ....... 84" ceiling height is only 7'. Since many men, and some women, are taller than 6' a ceiling fan is not really an option. ....... I am curious as to how well the AC system will work with the cold air being pumped UP instead of just falling down.?? Cold air blowing up would probably circulate the air more than blowing down. The cold air would go up toward the ceiling and move around the air there before falling back down to the floor returns.

RE: electricial 30 to 50 amp connection

The adapter works fine as it only uses one of the 50 amp breakers. You are still limited to 30 amp by your rig however. And 30 amp really means 24 amps since all breakers are limited to 80% of their rating for continuous power. ............. Circuit breakers are not limited to 80% of their rating. They will operate at 100% of their rating continuously without tripping. Only after they exceed the rating printed on the breaker will they trip. Circuit breakers for any given circuit are supposed to be sized to operate no more than 80% of the rating. But, again, that does not mean they will trip at 80%.
