10 Point Meter Pan Wiring Diagram | A Complete Guide

A 10-point meter pan is a type of electrical panel used to measure and distribute power to a building or other structure. It usually has ten terminals that connect the incoming power lines, outgoing power lines, and the ground wire.

Typically, a 10-point meter pan contains the following wires:

1. The electric company has three incoming power lines (L1, L2, and L3).
2. T1, T2, and T3 are the three incoming electricity lines to the building or structure.
3. 1 neutral (N) wire
4. 1 G ground wire

These are the wires that need proper wiring to ensure that a 10-point meter pan is working properly. Now let’s get to know more about the wiring of it.

2. Connect the incoming electricity lines to the meter pan’s T1, T2, and T3 terminals.
3. Connect the neutral wire to the meter pan’s N terminal.
4. Connect the ground wire to the meter pan’s G terminal.

What Are the Safety Measurements That You Should Take While Wiring a 10-Point Meter Pan?

The safety measurements that you must always take while wiring a 10-point meter pan are:

1. Before making any connections, always cut off the electricity to the meter pan.
2. For all connections, use the appropriate wire gauge and insulation type.
3. Check that all connections are snug and secure.
4. Before resuming power, check the wiring to ensure everything is in good working order.

Do I Need to Obtain Permits for a Meter Pan Installation?

Yes, a permit is required to modify or install your meter pan. This ensures that the installation follows necessary processes to safeguard the safety of everyone in the building. Consider the worst-case situation, which no one wants.  

If an inexperienced electrician decides to take care of your wiring, the outcomes could be terrible for both your home and your health. Don’t make yourself a victim. Contact a licensed electrician.

How Does a Service Entrance Conductor Relate to the Meter Pan?

A service-entrance conductor is a wire that enters the service network. It connects the utility power to the meter pan and the service main disconnects. Understanding where the service begins and finishes is crucial in applying many code rules correctly.

Conclusion

If your meter pan has current transformers (CTs) or potential transformers (PTs), these must also be properly wired. Please seek the advice of an experienced electrician on this.
