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.
The increase in neutral amps after shutting off the breaker could be due to a phenomenon called neutral leakage. This occurs when there is an unbalanced load on the phases, causing some current to flow through the neutral even when the breaker is off. It may also indicate a fault in the electrical system that needs to be investigated by a professional.

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.
What is type of breaker for 41 amp's?
For a 41 amp load, you would typically use a 50 amp circuit breaker. The general rule is to select a breaker size that is 125% of the continuous load amps or equal to the load amps if it is not a continuous load. In this case, 41 amps is considered a continuous load, so you would round up to the nearest available breaker size, which is 50 amps.
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.
How do you find out how big your main breaker box is?
You can determine the size of your main breaker box by looking at the number of circuits it can handle. A typical residential main breaker box is usually 100 amps, 150 amps, or 200 amps. You can also check the label on your breaker box or consult with an electrician for assistance.
How can a 30 Amps fuse for a shower of 9.5KW be replace with a 40 Amps fuse on RCD trip?
If the current safety requirement is 30 amps, you can;t run if off of a larger circuit breaker. It violates NEC and is very unsafe. If the current requirement is 40 amps , it will continuously trip a 30 amp breaker because it is too small of a breaker in electrical requirement.
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.
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 type of breaker for 41 amp's?
For a 41 amp load, you would typically use a 50 amp circuit breaker. The general rule is to select a breaker size that is 125% of the continuous load amps or equal to the load amps if it is not a continuous load. In this case, 41 amps is considered a continuous load, so you would round up to the nearest available breaker size, which is 50 amps.
What is 6InA in circuit breaker?
61 nano-amps is 0.061 milliamps or 0.000061 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.
What size circut breaker for 10-2 wire?
A #10 wire has the capacity for 30 amps. No breaker larger than 30 amps should be used to protect the circuit.

240V drop black red white bare on a 50A CB installed on the main power panel you want to split ths into two separate 120V circuits using the white as neutral for both will the 50A cb function normally?
It Will To The Exception That It Will Take Over 50 Amps To Kick The Breaker. You Will Have Two Circuits Protected By A Double Pole Breaker. You Could Remove The Strap On The Breaker That Holds The Two Together Giving You 25 Amps Per Circuit. ie One Breaker For The Black Wire And One For The Red Wire. Good Luck No, you will need to remove the double-pole breaker and install a separate breaker for each circuit, preferably no more than 20 A. The neutral and bare grounding wire can serve both circuits.
