- Select a location for the sub meter. It should be close to the electrical panel and easily accessible for reading.
- Turn off the power to the circuit that will be served by the sub meter at the main breaker panel.
- Remove the cover of the circuit breaker panel.
- Locate the wire for the circuit to be metered. It will be attached to one of the breakers in the panel.
- Cut the wire feeding the breaker with a pair of wire cutters.
- Strip 1/2 inch of insulation from the end of each wire using wire strippers.
- Connect the black wire from the sub meter to the black wire from the breaker panel using a wire connector.
- Connect the white wire from the sub meter to the white wire from the breaker panel using a wire connector.
- Restore power to the main breaker panel.
- Mount the sub meter on the wall using the provided bracket.
- Hang the provided current transformer on the wire feeding the breaker. The current transformer attaches to the sub meter with a magnet.
- Read the current transformer installation instructions to properly calibrate the sub meter.

How does an electric sub meter work?
In order to understand how an electric sub meter works, it is necessary to understand the principle of operation for a basic electricity meter. An electricity meter is a device that measures the amount of electric energy consumed by a residence or business. The basic operation of an electricity meter is relatively simple. It consists of two basic components: a disc that is rotated by the flow of electricity through the meter, and a set of gears that convert the rotational motion of the disc into the appropriate unit of measurement (usually kilowatts per hour).
The disc in an electricity meter is called a “blade.” The speed at which the blade rotates is directly proportional to the amount of electricity flowing through the meter. The number of revolutions per minute (RPM) of the blade is recorded by the meter’s gears, which are connected to a pointer that indicates the total kilowatt-hours (kWh) of electricity consumed.
An electric sub meter is essentially the same as a basic electricity meter, but with one important difference: the sub meter is designed to measure the electricity consumption of a specific appliance or group of appliances, rather than the total electricity consumption of a residence or business. This is accomplished by installing the sub meter in line with the wiring for the appliance (or group of appliances) to be monitored.
The most common type of electric sub meter is the plug-in sub meter, which is simply plugged into an available electrical outlet. The appliance (or group of appliances) to be monitored is then plugged into the sub meter. The operation of a plug-in sub meter is the same as that of a basic electricity meter, except that the sub meter will register only the electricity consumed by the appliance (or group of appliances) that is plugged into it.
Another type of electric sub meter is the whole-house sub meter, which is installed in the main electrical panel for a residence or business. Whole-house sub meters measure the electricity consumption of all the appliances and devices in a dwelling. The installation of a whole-house sub meter requires the services of a qualified electrician.
How do you set up a prepaid sub meter?
Prepaid sub meters can be used for residential or commercial customers who want the convenience of not having to worry about their power being shut off due to nonpayment. In order to set up a prepaid submeter, you will need to have an account with the utility company and be up to date on all payments. Once you have an account, you will need to contact the company to have them install a prepaid meter at your location. Once the meter is installed, you will need to add money to your account in order to keep the power on. The amount of money you add to your account will be based on your power usage.
Can I install my own power meter?
There is no definitive answer to this question since it depends on the particular power meter and your home’s electrical system. However, in general, it is generally not recommended to install your own power meter. This is because power meters can be complex devices, and improper installation can lead to serious electrical problems. If you are unsure about whether or not you can safely install a power meter, it is best to consult with a licensed electrician.
What is a sub metering system?
A sub metering system is a device that helps to measure the electricity consumption of individual appliances or devices within a household or office. It is usually installed near the breaker box and has a separate meter for each appliance or device that it monitors. This allows users to see how much electricity each appliance or device is using, and to make informed decisions about how to conserve energy.
What tools do I need to install a sub meter for electricity?
If you want to install a sub meter for electricity, you will need a few tools. First, you will need a voltmeter in order to measure the voltage of the circuit that you will be tapping into. Second, you will need a wire stripper in order to strip the insulation off of the wires that you will be attaching the sub meter to. Finally, you will need a drill in order to make the hole for the sub meter’s wire to pass through.
How do I wire the sub meter for electricity?
There are a few different ways to wire a sub meter for electricity, but the most common and easiest way is to simply connect the two hot wires from the main meter to the two hot wires on the sub meter. Then, connect the two neutral wires from the main meter to the two neutral wires on the sub meter. Finally, connect the ground wire from the main meter to the ground wire on the sub meter.
How do I test the sub meter for electricity?
The first step is to identify the main power supply coming into the building. This will be the total amount of power that is distributed to the various sub-meters. The next step is to determine the load on each sub-meter. This can be done by using a meter that measures the current and voltage on the circuit. The last step is to verify that the sub-meter is reading correctly by comparing the readings to the main power supply.
What are the benefits of installing a sub meter for electricity?
There are many benefits to installing a sub meter for electricity, including:
1. Increased accuracy of electricity usage data – This can lead to more accurate billing and a better understanding of how your business uses electricity.
2. Ability to track electricity usage by specific equipment or areas – This information can be used to make informed decisions about where to allocate resources or make changes to improve efficiency.
3. opportunities to reduce overall electricity consumption and costs – Having detailed data on electricity usage can help businesses identify ways to reduce their consumption and save money.
Are there any risks associated with installing a sub meter for electricity?
Yes, there are risks associated with installing a sub meter for electricity. These risks can include:
-damage to the electrical system or wiring in your home
-injury to yourself or others if you attempt to install the meter yourself
-shocks or electrocution
