I don't know what may be wrong with your breaker ... I believe I would replace it or have it looked at by a professional. Your load is pretty well balanced ...

You certrainly don't want to have a prblem with it while you arent @ home.

1998 Thor Wanderer travel trailer. Has no breakers or fuses. How can I find out what to install?


You have a main breaker in the panel, most often 30 amps. (Possibly 50, depending on your hookup. If your cord you plug in outside has 3 prongs it's 30 and 4 prongs it's 50) then you have a 20 amp breaker for your air conditioning and a 15 amp for your microwave or outlets. As far as fuses go, usually you have a 30 or 40 for the main converter fuse(s) and then mostly all 15's in all the other slots.

Main breaker doesnt stay turned on


Tripping of the main breaker could be an indication of a short or an overload. To check for an overload you will need an amprobe to test the amperage load on the breaker. Turn all the secondary breakers off. Attach the amprobe by clamping it around one power wire. Turn the breakers on one at a time and check the reading of the amprobe. Most breakers will handle about 80 % of the breaker rating before tripping. If it trips below this point the breaker may be weak and will need to be replaced. If the amprobe pegs out at any time and the breaker trips the secondary breaker that was last turned on probably has a short in its wiring somewhere. Cuasing the breaker to trip. Underground wirng that has gone bad can sometimes take a while to trip the breakers so if there is any underground feeders it may be more difficult to track down a short. If the problem is an overload check both hot wire to see if the load is equal if the load is a lot higher on one leg than the other switching some circuits to the lower side may help. If the total load is just too high you may have to increase your service to a larger size. Hope -this helps

You can add the breaker.
The key is total electric use.
As long as total consumption does not exceed amps shown on main breaker, then the new 40A breaker installation is ok.
If total consumption exceeds main breaker, then the main breaker will start to get hot and then trip.

Put hand on main breaker and feel for warmth.
The main should not feel warm.
Consider upgrading to 150A or 200A service.

My question is on the main 100 amp breaker it has one slot on each side of the breaker .so one hot wire goes on the right side and one goes on the left side ? its a little confusing because usually both...


A main breaker accepts two inputs which are 180 degrees out of phase. If this is in the US, then each phase is approx 110V relative to ground (or neutral) and the the two phases are approx 220V relative to each other. There are two hot bus-bars in the panel, running vertically one for each phase of the main breaker. If you look at how these bus bars are connected to the branch breakers, you will see that every-other breaker slot in the panel is connected to one phase or the other. So if you have a 220V branch breaker, say for the stove, this is really two breakers together, one for each phase. These 220V branch breakers do have output lugs right next to each other. The main breaker is similar in that it is also two breakers connected together. But because the main breaker is mounted at the top and is as wide (or nearly as wide) as both sets of branch breakers (down the left and down the right) it is generally more convenient to wire the inputs to the left and right side of this main breaker. But the location of the input lugs to the main breaker is arbitrary. There may be some models where the inputs are adjacent to each other. If you have any doubt, do a continuity test on the main breaker (while it is NOT installed) to confirm that that each input lug is connected only to one output clamp (that is, where it connects to it's bus-bar.) I hope this helps, please vote if it did. Good luck, Al K

I replaced all parts but water heated won't get hot


You have electric water heater.
You replaced elements and thermostats but heater still won't work.
And tank was completely full of water, and water was running out of a faucet before turning power ON.
If elements are not fully immersed in water, they will instantly burn out.
If upper element is burned out, then tank will have NO hot water.
If lower element is burned out, and upper element is not burned out, then tank will have some hot water.
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-it-works.html

If elements did not burn out, then that leaves 1 main suspect: the electricity.

1) Push in ECO red reset button on upper thermostat. If ECO is tripped out, then heater will not work.

2) Click circuit breaker all the way one direction and then back the other direction to make sure breaker is latched.

3) If tank has 2 elements, then it is 240volt.
If 1 leg of 240Volt circuit is not working, then 240V appliance will not work.
240Volt circuit needs both hot wires to complete the circuit:
http://waterheatertimer.org/How-to-wire-EH40-hot-water-heater-timer.html#120-240

Buy cheap multimeter from Home Center and set dial to 240-250-277VAC
Tape tester leads to woods sticks to keep hands away from power.
Power is ON
Test across top 2 screws on upper element should show 220-240 volts.
If you have 240 at top two screws, then skip down to step 6.
If no reading across top two screws, then move to top of tank.

4) Open connection point where wire connects to heater.
Test across both insulated wires should get reading of 220-240 volts.
If no reading, move to circuit breaker box.

5) Mark water heater breaker.
Turn off all breakers except water heater breaker and main breaker. (and breaker to light fixture where box is located)
Do not hold or touch or lean against anything metal.
Stand on dry boards and wear dry clothes.
If main breaker is OFF, the big wires that connect to main breaker are still HOT.

Remove box cover.
240Volt breaker has 2 wires connected with screws.
Test across both screws for 240Volt.
See if wires are loose.
If there is no reading, then breaker is not working on one leg.
To double check, move water heater wires to another same-size 240V breaker and then put ear against water heater to listen for bubbly-fizzing sound.

6) If you are getting 240 to water heater, then wire inside tank could be loose.

Can i replace the main (100 amp) is a sq d QOC20u100F panel with a 200 amp main--i will up grade meter socket and entrance cable to 200 amps cwalker


First the part number QOC20U100F is a flush mount panel cover. The panel you have is most likely a :QO116M100. No you cannot replace the breaker as the bus in the panel is only rated for 100A. In addition I believe this is a 20CKT panel. If you're gonig to a 200A service you'd probably want more spaces than that. Home Depot and Lowes both carry 200A panels with starter set of breakers at reasonable price. The QO panels are a bit better than the Homeline
Here is a link to manual for their panels. :

I have a 12 year old 40 amp rated hot tub wired with a br50spa gfi to a 40 amp breaker in electric panel. Is this ok?


As long as it is wired with at least #8 wire your 40 amp breaker should be fine. The 50 GFI could not pull over 40 amps from the main panel.

Ben, you are on the right track. To upgrade the breaker, first look at the main house breaker panel and determine if allowing more current through main breaker will be taxing it too highly (will 20 more amps exceed my main breaker limit...what is the main breaker current trip at?) Then look at the wire size leading away from the 40 amp breaker to outside. If it is 6 gage copper or 4 gage copper-clad aluminum wire, you are ok to upgrade. Any smaller wire size could be unhealthy.
