Eaton Group Metering

More Information about Eaton Group Metering

When deploying electrical group metering from Eaton, installers can select enclosures rated NEMA 3R, which are suitable for both indoor/outdoor applications where protection from the elements is required. Group metering options include aluminum bus construction and breaker construction that can be customized to project specifications, including commercial metering.

A solid metal barrier separating the meter socket from the tenant main breaker and wireway sections offers essential protection for the unmetered bus, preventing unauthorized access and ensuring electrical safety. This robust barrier design minimizes the risk of accidental contact or tampering with unmetered components, which is crucial for maintaining the integrity of the electrical system.

FAQs

What type of group metering includes single phase, UL listed single meter sockets and main service modules as the core features?

Residential and light commercial group metering typically includes single-phase, UL-listed single meter sockets and main service modules as core features.

How to Use a Multimeter

Measuring AC Voltage

Set the dial to the AC voltage symbol and plug the red probe into the voltage port. Place the red probe into the hot terminal block and the black probe into the neutral terminal block. Make sure the probes are fully seated to something that can conduct electricity, like the screws on the terminal blocks. The measurement is taken in parallel with the load.

Measuring DC Voltage

Set the dial to the DC voltage symbol and leave the probe in the same port as it was for the AC voltage measurement. Place the red probe to DC positive and the black probe to DC negative. The measurement is taken in parallel with the load.

Measuring Current or Amperage

Set the dial to either milliamps or amps. Move the red probe to the DC amp port. The multimeter is now set to measure DC current. Remove the wire that is sending power to the load and place one probe on one end and the other probe on the other, to complete the circuit, allowing power to bypass the load. The meter will break the circuit and measure the current in series with the voltage source. This allows the meter to measure the current that is going to the load.

Measuring resistance

Make sure that the load is disconnected from the electrical circuit, otherwise, the resistance measurement will not be accurate. Set the dial to the ohm symbol and place the red probe into the voltage port. Place one probe on one conductor and the other probe on the other. Take the reading.

Measuring Continuity

Meter settings stay the same as previous measurements, with the addition of pressing the audible button. Place the probes anywhere on the electrical circuit. An audible tone will sound if there is a continuous, point to point connection. If there is no sound, there is break in the electrical connection, possibly caused by broken or frayed wires.
