    since you changed the safety switch, i would try to remove one outlet at a time and retry the switch each time. it may take alittle while if your not in a hurry. this may help isolate or find the problem before calling and spending more money again. just a suggestion, best of luck. Steve

There might be a short circuit in your wring for that circuit.
You can unplug all your electrical items from that circuit.
See if the circuit still turn off.
If it does, it could be the wring or the equipment that is permanently wired in.
If not, you can plug in one item at a time, turn it on to determine which electrical item is defective.

How do I change my American standard horizon hx851 to receive Australian channels


To change this radio from Canadian to USA or to International frequency band plans, hold down the [16/9] key and press the [CLR (WX)] key. The band will change from Canadian, to USA, then to International on each press.
Australia uses the International marine band plan.
Have fun.

Circuit breaker trips frequently. It is a double 20 amp switch.


Is this breaker connected to water heater?

1) A double 20 amp breaker is called a 240Volt breaker.
20 amp breaker is actually rated for 16 amps for safety margin.
It is also important that this breaker have 12 gauge wire which is color-coded yellow.
Look at label on side of water heater for wattage of unit.

2) For example 4500 Watt water heater is typical.
4500 watts divided by 240Volts = 18.75 amps which is nearly full capacity for the 20 amp breaker, and is slightly above the safety margin.
http://waterheatertimer.org/B220C.html

3) If breaker is getting old, and it works at full load each time water heater is on, it can wear out.
Open circuit breaker box and replace breaker:

4) You can also move circuit breaker wire to another same-size breaker and see if problem continues.

1 Answer

Purchased "Reliance Lowboy electric water heater"


The water heater has two 4500 watt elements.
However both elements are not turned-ON at same time
So the water heater is 4500 Watts

Volts x Amps = watts
Amps =watts divided by volts
Amps = 4500 Watts divided by 240 Volts
Amps= 18.75

So that says a 20 amp breaker ... except for the 80% rule
80% rules says for safety, your Amp rating should be multiplied by 80%

20 amp breaker X 80% = 16 amps
20 amp breaker is actually safe for just 16 amps, and your water heater draws 18.75 amps.

The calculation shows you need a 30 Amp breaker.
30 Amp breaker requires 10 gauge wire.

How to hook up single pole shunt tip breaker in panel


To be very safe, turn OFF your Main circuit breaker prior to doing this. This IS really important! You asked how to hook up the breaker, so I'm going to assume you already installed this. The first wire that you'll want to land under a screw is your ground (green) wire. This wire should be where all your ground/green wires are. Next, you're going to bring your white (neutral) wire to the neutral bar.  You should see other white wire's terminated (attached under screws) there. Then, bring your colored (ie usually a black or red) wire and attach it to your circuit breaker. Make sure that you are using a #10 guage wire. This wire guage is rated for 30 amps. If you're using a 20 amp circuit breaker, then use a #12 guage wire. And a #14 guage wire for 15 amp circuit breaker. Using these wire guages satisfy all electrical requirements (codes). Now, leave the circuit breaker in the OFF position, and close up your panel. After closing it, then turn ON your Main circuit breaker. If everything is fine, great! Before you turn on your circuit breaker, make sure the switch, device, receptacle (unplugged), is OFF. Then go to your electric panel and turn ON the circuit breaker. If the breaker holds (doesn't trip), then try your switch, device, or receptacle to see if everything works. One last thing to remember is, if you're using a 30 amp circuit breaker, then the device on the other end should only draw up to 24 amps. Meaning, don't put a 30 amp cir. brkr. on a 20 amp recectacle, switch, or device. For a 20 amp cir. brkr., 16 amps is the maximum load you can put on this. I hope this helps you. Just read it through once, and then highlight the main parts of this and you should do fine. Good Luck, and feel free to contact me if you'd like further assistance. - Jim

Where is the monitor switch?


The job of the monitor switch is to prevent the oven from cooking while the door is open.

If there is a problem with the door switches or door switch alignment that could allow that to happen, the monitor switch stands ready like a crowbar to ensure that the fuse and/or house circuit breaker will blow to interrupt power to the oven.

The service manual for this oven is here.

Since you're asking, I would bet you have an issue with your door switch or door switch mount, such as:

- the oven will count down but not actually start cooking when you press "Start". This is almost always a bad primary interlock (bottom door switch in this model).

- the fuse or breaker blows when you open or close the door. This is probably a sticky door switch or loose or broken door switch mount.

See http://www.microwavedisplay.com/safety.txt , http://www.microwavedisplay.com/disassembly.txt and http://www.microwavedisplay.com/doorsw.txt

When I plug in my laptop, a vaccuum, or some other electrical item like that, the circuit breaker trips.


have you got anything else plugged into the circuit? e.g kettle, toaster? if so you could be overloading the circuit. also don't know what country you are in but in Australia it is a 16 amp circuit breaker with 2.5mm cable. if your Circuit breaker is less than 16 amp check with an electrician and he could replace it and fix your problem. if it is already 16 amp you are most likely overloading the circuit by drawing to much amperage from the circuit.

Every time I turn on the appliance it blows a fuse


A washer requires a dedicated electric outlet to operate properly. It is possible that the plug you have is part of another circuit and has some other high ampere drawing devices connected to it. Check to see if any other items are affected when the circuit trips (or fuse blows).

If you truly have actual fuses instead of ciruit breakers, make sure the fuse you are replacing is a slow blow type rated at the proper amperage for the circuit.

If you have circuit breakers, you might have to have a separate 20 amp dedicated branch circuit added to power the washer. (USA/Canada)

Without further details of the specifics of your situation, that is the advice to check first.

Electrical


Circuit breakers are designed to protect life and property. Do not use an appliance that overloads the breaker. If it is popping a 15 amp breaker try it on a 20 amp, if it does not trip the 20 amp breaker measure the amperage. If the actual amperage exceeds 16 (80%) of the overcurrent device or the device exceeds the Wattage stated on the device. Repair or replace it.
