This reading must have been taken off of the distribution panel's main neutral conductor. The neutral conductor of a distribution panel carries the unbalanced current. If a panel is perfectly balanced there will be zero current on the neutral conductor. With loads being applied and removed from the distribution panel as equipment is turned on and off the neutral current will change. If the breaker that you turn off while the panel is in perfect balance when it is on, when it is turned off, it will put the panel into an unbalanced condition again and this is the current that you will be reading.
This is the reason that the electrical code allows a reduced neutral conductor size on distribution calculations. On engineered projects the circuit must be connected to the correct breaker position as shown on the electrical blueprint, as the engineer has already calculated the loads to produce the lowest possible current on the systems neutral conductor.

What's a double breaker 20 amps and 30 amps?
A double breaker is a breaker that has 2 switches on it. One of the switches is 20 amps and the other is 30 amps.
How many volts can you draw off of a 15amp breaker?
It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.
What size wire and breaker do you need for a 5000 watt garage heater?
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
What is the maximum amps each phase conductor carries on 200 amp residential service?
If the mains is a 200 amp two pole breaker each leg can carry up to 200 amps in relationship to the common neutral of the service.
What is the continuous current draw on a 20 amp circuit breaker?
Depends on what you have connected to the circuit. It is less than 10 amps or the breaker would trip. A rule of thumb is you design for about 80% load related to the breaker. For 20 amps that would equal 16 amps.
What's a double breaker 20 amps and 30 amps?
A double breaker is a breaker that has 2 switches on it. One of the switches is 20 amps and the other is 30 amps.
Is it necessary to balance a house fuse panel to save electricity and if so why and how is it done?
A balanced house panel should be the ultimate goal. It will not save you electricity as the watt meter on the house monitors the use of power from both legs of the incoming power. To balance a panel you want the current from L1 to Neutral to equal L2 to Neutral. The neutral carries the unbalanced current between L1 and L2. A perfectly balanced panel will have no current on the neutral. It is done by knowing what the current draw is on every breaker. Then they are physically positioned so that they equal each other on the opposite leg. e.g. breaker 1 on leg L1 = 5 amps, breaker 2 on leg L2 = 10 amps, breaker 3 on leg L1 = 10 amps, breaker 4 on leg L2 = 5 amps. Total up all amperages on L1 and then on L2 , if they are equal then the panel is balanced with no current on the neutral.
What is KA in Circuit Breaker?
KA stands for kilo-amps, or thousands of amps. Thus a 2KA breaker means it will trip when the load exceeds 2,000 amps.
How many volts can you draw off of a 15amp breaker?
It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.

If a breaker is rated for 30 amps and is 2 poles is it ok to put an appliance that draws 50 amps?
The number that is on a breaker is the amount of amperage that the breaker can deliver before it trips. This is the same regardless of how many poles the breaker is.
What is 6InA in circuit breaker?
61 nano-amps is 0.061 milliamps or 0.000061 amps
What is the continuous current draw on a 20 amp circuit breaker?
Depends on what you have connected to the circuit. It is less than 10 amps or the breaker would trip. A rule of thumb is you design for about 80% load related to the breaker. For 20 amps that would equal 16 amps.
What breaker to use in a bedroom that holds up to 15 amps with 120v?
15 amp breaker.
What is neutral inversion?
If the consumers metalwork is not bonded to the neutral a direct earth fault would result in a current of 20 amps flowing.This fault current will probably be carried by a 16 amp fuse or citcuit breaker and returned to the neutral via electrodes this will force the neutral conductor up to a potential of 200 v above earth this is known as neutral inversion
How much 1200 watts on one breaker?
Not a whole lot. Assuming that is 120 volt power, 1200 watts would be 10 amps. A standard breaker is 15 amps.
