You need to check the current rating of your heat strips. If it is more than 60 amps then you need a bigger breaker. If 60 amps or less then your heat strips are going bad. Also make sure your fan turns smoothly without any wobble.

1) Match wire and breaker:

http://waterheatertimer.org/Color-codewire.html

http://waterheatertimer.org/See-inside-main-breaker-box.html

2) 7000 watts divided by 240 volts = 29.1 amps.

30 amp breaker x 80% safe maximum = 24 amps.

This means you should use 8 gauge wire and 40 amp double pole breaker for 240volt

3) 7000 watts divided by 120 volt = 58.3 amps.

60 amp breaker x 80% safe maximum = 48 amps.

So use 70 amp breaker and #4 wire.

1) Move wire to another same-size circuit breaker to eliminate bad circuit breaker as suspect.

Do NOT increase size of breaker or it will cause fire.

http://waterheatertimer.org/How-to-replace-circuit-breaker.html

http://waterheatertimer.org/Troubleshoot-household-electricity.html

2) Put hand on each appliance and outlet to see which ones are warm. Outlet should never be warm or hot. Replace outlet. Inspect wires for loose and burned connections.

3) If the breaker is good, then add up total watts being used by checking watt rating on each device. 100 watt light bulb is 100 watts. Big screen TV has a label that shows 300 to 500 watts. Computer has label. Space heater has label showing 1500 watts. Iron has a watt rating label. Take total watts and divide by 110Volts and this will give amp load. Total watts used = 2000 and then divide 2000 by 110 volts = 18.8 amps

Compare amp load with circuit breaker.

20 amp circuit breaker has 80% safe maximum, or 16 amps.

If amp load is 18.8 amps, then 20 amp breaker is starting to get hot, and weak breaker will start tripping.

If amp load is 18.8 amps, and breaker is 15 amps, then you are overloaded and breaker is feeling the heat, and tripping because of heat.

Solution is to reduce amp load.

4) If you have short circuit, that can also trip breaker.

Unplug everything and then plug things back in slowly to see which plug or appliance is causing the problem.

Hi - I'm an electrician and can help you with your question.

A BR2100 circuit breaker is a 2 Pole 100 Amp (for the part number "BR2100", the "2" indicates the number of poles and the "100" indicates the amperage) circuit breaker. It can be installed in a single phase or three phase 120/240 VAC system panel*that specifically lists the BR series breakers as acceptable for use.*

A BR260 A BR2100 circuit breaker is a 2 Pole 60 Amp (the part number BR260, the "2" indicates the number of poles and the "60" indicates the amperage) circuit breaker. It can be installed in a single phase or three phase 120/240 VAC system panel*that specifically lists the BR series breakers as acceptable for use.*

It is not possible to have a BR2100 rated for 60 amps, 1 or 3 poles, or a BR260 rated for 100 amps, 1 or 3 poles.

*It is not permissible to install any circuit breaker brand or type in any panel that does not specifically include it on a list of acceptable circuit breakers.*

Circuit breakers are designed to carry 80% of the amperage rating.

To**determine the load **a circuit breaker** **can carry, multiply the circuit breaker amp rating by 80%. This means that if you need to supply more than 80 amps, you cannot use a 100 amp circuit breaker. A higher rating is required. A BR2110 would be acceptable for loads greater than 80 amps, but less than 88 amps because the formula above says: 110 amp x 80% = 88 amps.

*To ***determine the breaker size**, *determine the load (by measuring with a meter or obtaining amp rating of the load from the data plate) and multiply it by 125%*. Using the same numbers in the example above; assume an 88 amp load. 88 amps x 125% = 110 amp circuit breaker. The 60 amp breaker is acceptable for up to 48 amps because 60amps x 80% = 48 amps. A 48 amp load needs a 60 amp breaker because 48 amps x 125% = 60 amps.

I hope this helps and good luck!

Always match breaker and wire size:

http://waterheatertimer.org/Color-codewire.html

http://waterheatertimer.org/How-to-replace-circuit-breaker.html

Feel if breaker is getting warm.

Listen for crackling sound.

Breaker is tripping.

Move wires to another same-size circuit breaker and see if problem continues.

Check watt or amp load on breaker.

For example water heater label shows 4500 watt non-simultaneous.

4500 watts divided by 240 volts = 18.75 amps.

You might think 20 amp breaker was good in this case.

However electricians use 80% safe maximum.

20 amp breaker x 80% safe max = 16 amps.

Water heater is 18.75 amps, so install 30 amp breaker.

30 amp breaker uses 10 gauge wire.

This means wire to breaker will run cool and not get hot, so breaker lasts longer, and there is more efficiency.

Using 80% safe maximum rule protects home, reduces heat wear on breakers and breaker box so everything lasts longer.

Breakers trip because of heat.

When heat from wire exceeds breaker rating, it trips.

Something is causing heat on the wire, wire is too small for the amp draw, there is short circuit, or breaker is bad.

Replace breaker and/or test wire.

Put amp-meter on wire and read amp draw through wire.

Amps cause heat. That's why high voltage lines from power station are high-volt-low-amp so there is no heat loss with long distance transmission, until transformer at home converts electricity to lower volts and high working amps with enough power to run electrical devices.

Same is true for AC and DC circuits.

If amp reading on wire exceeds rating on breaker for length of time, then breaker will trip.

The fact that the breaker lets current (amps) to flow for a period of time before tripping is because the breaker is probably rated for slow-acting, or it takes a while for amp draw to heat the wire.

Following image shows amp-meter that clips over wire to get amp reading.

Look at rating plate on side of unit for Volts, Amps, Watts.

Volts x amps = watts.

If unit is 240Volts, then you need double-pole 240Volt breaker

If unit is 8500 watts at max power, then 8500 watts divided by 240Volts = 35 amps.

What size breaker for 35 amps?

When electricians figure load rating for breakers, they use the 80% rule.

40 amp breaker x 80% = 32 amp safe maximum load for 40 amp breaker. Use 8 gauge wire with 40 amp breaker.

50 amp breaker x 80% = 40 amp safe maximum for 50 amp breaker. I use 6 gauge wire with 50 amp breaker.

60 amp breaker x 80% = 48 amp safe maximum for 60 amp breaker. Again, use 6 gauge wire with 60 amp breaker.

How to connect wires to unit.

First of all, all outdoor HVAC units require power cut off located next to unit.

This lets the mechanic, or service tech turn power off to work on unit, even if the mechanic does not have access to main breaker box.

Next, open unit to see where wires connect.

If unit has wires, then connect both hot wires from 240 breaker to the wires inside unit. Connect bare ground wire to green ground screw.

If unit has terminals. The terminals will be labeled L1 L2. Connect each hot wire from 240Volt breaker to either one of the screw terminals. Then bare ground goes to green ground screw.

Copy following links for basic illustrations connecting wires to terminals, and to breakers, and selecting wire size.

Look at rating plate on motor.

Look for volts, watts, amps.

Figure with Volts x Amps = Watts.

Amps = Watts divided by Volts

1 hp horsepower is 756 Watts.

Lets say you have 120Volt 2hp motor

So 2 horsepower motor draws 1500 Watts

Amps = 1500 Watts divided by 120Volts = 12.5 amps = so you need 120Volt 15 amp breaker with at least 14gauge wire (as long as motor is located within 50 feet of breaker.)

If motor is farther away, then you need 20 amp breaker with 12gauge wire.

Look at circuit breaker rating.

If motor is 240 and breaker is 120, then it will trip breaker.

If motor is 120 and breaker is 240, then it will trip breaker.

If breaker is for 15 amps and motor draws 20 amps then it will trip breaker.

Generally speaking, if motor and breaker are 120V, then black wire goes to black wire; white wire goes to white wire and green wire connects to bare copper wire.

If motor and breaker are 240V, then wire colors can be different. Black-red or Black-white from breaker connect to Black-red or Black-white at motor.

Add a comment. Say the motor rating and color of motor wires. Say the breaker size and color of wires coming from breaker and I will help you wire the device.

If you don't have an AMP clamp to measure the amount of AC current draw. Then I would replace the breaker with a new 30amp. If the electrical panel is a sylvania or Zinco then that is most likely the problem! Those panels use the same breaker type and are terrible at having breakers going bad and tripping premature. If it is one of those type of breakers better dig deep in your wallet as those breakers run $1.25 to $1.50 per amp !

Nov 30, 2009 | Whirlpool WED5300S Electric Dryer

If the breakers are 20 amp and the panel is rated at 100 amps, only 5 breakers. if the panel is 200 amp, only 10, 20 amp breakers and so on
