Group Metering

Group metering is an electrical distribution approach that allows for multiple meters to be housed in a single unit. This can be particularly beneficial for multi-tenant buildings, commercial complexes, or any location where power usage for separate areas or parties needs to be individually measured. Group metering systems are available in single phase and three phase options, providing flexibility for a wide range of electrical needs.
A key element in these systems is the meter breakers. They combine the functions of a meter socket and a circuit breaker into a single unit, streamlining the metering and distribution process. The breakers can vary in type, such as the Type BR, which is a specific kind of meter breaker that comes with certain features and benefits.
Another important aspect to consider in group metering is the bus rating, which is a measure of the system's electrical capacity. This ensures that the system can handle the electrical load that will be placed on it. Some systems also offer an aluminum bus, which can be lighter and sometimes more cost-effective than other materials.

Sockets are essential in these systems as they are the physical interface where the meter connects. They are designed to be modular, allowing for customization based on the number of tenants or the electrical requirements of the property. This modularity also allows for easier maintenance and potential future expansions of the electrical system.
The bypass feature is another noteworthy aspect of group metering systems. Bypass mechanisms allow for a meter to be removed or serviced without disrupting the electrical supply to the area it serves. This is crucial for commercial settings where uninterrupted power is often required.
Accessories can further enhance the functionality of group metering systems. These may include additional components for overhead configurations, ring setups, or even specific contact elements for improving the system's reliability and performance.
What is a Circuit Breaker?
Magnetic Breakers
Magnetic Breakers are designed to react to short circuits or sharp spikes in voltage and current. The more current that passes through the breaker's electromagnet, the stronger the magnet becomes. When the current exceeds the rating for that particular breaker, the magnetic force becomes strong enough that it will pull the contact back and disconnect it from the other contact, disconnecting power from the device.
Thermal Protection Breakers
Thermal Protection Breakers protect against a sustained overcurrent, or a higher current, for a longer period of time. Thermal protection uses a Bimetal strip that will bend the contacts away from each other to disconnect power. Thermal Magnetic Breakers are the most common type of circuit breakers. They combine magnetic technology to protect against short circuits or sharp spikes and thermal technology that protects against sustained overcurrent for a long period of time.
