Dedicated 20 amp outlet


Ideally you should run the line straight from the circuit breaker out to your hot tub, but if the line running from your circuit breaker to the box you're using now is 20amp. you can absolutely connected to that. to be up to code it cannot be an open box it needs to be closed After you wire in your 70ft connection. (that's assuming the box that you're using is dedicated already to your hot tub) then the only difference would be is your using extra line and costing you tenths of a penny extra and electricity per hour.

Duo therm mod. 57915 air conditioner seems to work good , runs for 4-5 minutes then kicks breaker , was kicking 30 amp breaker at camp ground , i've been working on connections to make sure its...


Unit may pull as much as 17-18amps when compressor starts up, but level out to 12-15 amps when up and running. Keeping in mind that is all relative to proper 120v incoming voltage, heavy enough wire to run the application etc. If your AC unit needs cleaning , it may draw an extra amp or 2 . With that said, when your at the park, first thing I'd question is their incoming voltage to RV, and try running fridge etc and anything else on propane if possible. The AC alone should not cause 30amp at source breaker to trip, before 15 0r 20 amp breaker in RV that is connected to AC trips. If it doesn't trip your breaker at home, and all is connected same at park, then I certainly would suspect bad breaker or voltage/wiring at park is the cause. P.S. I noticed you said you have 12 gauge wire (rated at 20 amps) connected to a 20amp breaker at panel, but RV is plugged in to a 15amp receptacle, I will assume with a 15 amp adapter from 30 amp plug. Do you see any hazard regarding 15 amp rating on receptacle? ( just a little advice.)

Installed a 12,000 btu LG window unit. Did not see that the plug was a standard 250v. I changed recepticle, and the manual said to be sure to have a 20 amp breaker, which there is. The unit comes on but...


What is the voltage of the unit? What is the voltage of the circuit? You say standard 250 V plug ... is that the rating or the configuration of the plug?

More specifically, your 12,000 BTU unit should be on a circuit of its very own to preclude over loading the circuit and causing damage to your AC.

I just purchased a souleus 12000 btu portable air conditioner. The unit works fine but keeps tripping the circuit breaker in my apartment. What causes this and can it be fixed or is it just the wiring in...


First, you need to determine what, besides the Souleus, is on that electrical circuit, and whether the circuit is 15 or 20 amp.

12,000 BTU A/C's tend to pull 10-12 amps, and they can peak just under 15 when the compressor starts. So a new, right off the shelf unit will max out a 15amp circuit. An older model with a worn out starting cap will demand even more amps at compresser startup.

LG Washer trips dedicated breaker


That to me seems like an electrical problem. Every now and again you can get a bad GFCI receptacle that will constantly keep tripping. I would also see that the GFCI is properly sized for the circuit. It needs to be a 20 AMP circuit (just dedicated to the washer) and a 20AMP GFCI receptacle. The way to tell is the 1 of the three prongs of the 20AMP GFCI will be in the shape of a "T" while a 15 AMP will have 2 straight prongs and the ground prong. Hope this ws helpful, don't go spilling any money into your washer without getting that fixed first, because it doesn't seem like a washer problem.

20 amp breaker pops with only a light (60watts) and a small tv on. samething occurs in another room with an iron and a light on, These items can't possibly be brawing 20 amps. Is there a problem with these...


I have been an electrician for 11 years and when these breakers came out in 2005 what a nightmare. These circuit breakers are extremely sensitive. They are designed to sense loose connections and to protect your house from fires caused by them. By increasing the load (ie. more lights or tv) it increases the size of the "arc" created by the loose connection and the circuit breaker trips before the 20 amp maximum. What I normally find as the cause is a loose connection in one of the receptacles or switches on the circuit. A lot of times, installers will use the "quick stab" inserts on the back of the outlets or switches instead of the side screws. Usually, if you "side screw" all of the receptacles and switches it will resolve the nuisance tripping. One other item that can cause them to trip is too many dimmers on the arc circuit but it doesn't sound like that is the problem you're having.

You must have too many things running on that circuit. Check your connection to the power box.Loose connection on the receptacle can cause the breaker to trip or too many things running on the same circuit. If the breaker is old it might need to be replaced.

Arc fault trips under load


Arc fault breakers are definitely a pain. First make sure the receptacles are made for a 20 amp circuit. Second vacuums, Curlers,and most appliances will trip your breaker since they create an arc or a short if you will to operate. That is exactly what these breakers are made for. To stop the arc. Apparently they never really thought the whole arc fault thing through. As per code in most of arizona you only need this breaker in bedrooms where this type of appliance is not used. They also are more prone to popping so make sure you aren't running something on each of the receptacles at the same time
