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.
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?
Simple. Your main electrical panel will have a "main breaker". This will be a two pole breaker, usually at the top of the panel. It will have a number on the breaker "handle" such as 150 or 200. This is the maximum number of amps your panel can supply. Most newer homes, 1975 and newer have a 200 amp service.
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 the purpose of a 30 amp double pole breaker in an electrical circuit?
The purpose of a 30 amp double pole breaker in an electrical circuit is to protect the circuit from overloading by shutting off the power if the current exceeds 30 amps.
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.
What is the maximum amperage capacity of a Siemens breaker that is rated at 200 amps?
The maximum amperage capacity of a Siemens breaker rated at 200 amps is 200 amps.
What is the maximum current rating for the circuit breaker, rated at 150 amps?
The maximum current rating for the circuit breaker is 150 amps.
What is the maximum amperage capacity of a 60A breaker and how does it affect the electrical circuit it is protecting?
The maximum amperage capacity of a 60A breaker is 60 amps. This means it can handle up to 60 amps of electrical current before tripping and shutting off the circuit. It protects the electrical circuit by preventing an overload of current, which can cause overheating and potentially start a fire.
What is the maximum current rating for the circuit breaker that can handle a load of 40 amps?
The maximum current rating for the circuit breaker that can handle a load of 40 amps is 40 amps.
What is the maximum current rating for a 2 pole breaker that can handle 25 amps?
The maximum current rating for a 2 pole breaker that can handle 25 amps is 25 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 the purpose of a 15 amp double breaker in an electrical circuit?
A 15 amp double breaker in an electrical circuit is designed to protect the circuit from overloading by shutting off the power if the current exceeds 15 amps. This helps prevent overheating and potential fire hazards in the wiring.
What is the maximum current rating for the circuit breaker required for a device that operates at 20 amps?
The maximum current rating for the circuit breaker needed for a device that operates at 20 amps is 25 amps.
