Utility Disconnect for Panel Upgrades: What Homeowners Need to Know

Why Is a Utility Disconnect Required?

The service entrance wires — the conductors running from the utility pole or underground feed into your meter — remain energized at all times under utility control. These wires carry full line voltage (typically 240V for residential service) and cannot be safely de-energized by simply turning off your main breaker. Only the utility company can disconnect power upstream of your meter.

During a panel replacement or service upgrade, the electrician must work near the service entrance conductors. The utility disconnect removes the voltage from these wires, making the work safe. Without it, the service entrance side remains live even with your main breaker off.

For a straight panel replacement with no amperage change (same size meter base, same service entrance conductors), some utilities allow the work to proceed without a full disconnect — using careful work practices with the main breaker off. But for any amperage upgrade, a full utility disconnect is always required.

How to Schedule a Utility Disconnect

The process varies by utility, but the general steps are:

1. Have your permit number ready. Most utilities require a valid permit number before scheduling a service work request. Apply for the permit first, then call the utility as soon as it's approved.
2. Call the utility's construction or service work line. Don't call general customer service — ask specifically for the "construction" or "electrical service work" department. This team handles scheduled disconnects, not bill payment or outages.
3. Provide your address, permit number, the current and new service size, and your preferred dates. Some utilities offer a window (e.g., "morning of Tuesday the 14th") rather than an exact time.
4. Confirm what the utility will do. The utility typically pulls the meter, disconnects the service entrance, and comes back after the work is done to reconnect and reset. Confirm whether you need to call them again for reconnect or if it's scheduled automatically.
5. Have the inspection scheduled before the reconnect. Many utilities require a passed electrical inspection before they'll reconnect service. Coordinate your inspection appointment before the reconnect date.

Do You Need a Utility Disconnect for a Same-Size Panel Replacement?

If you're replacing your panel with the exact same service size (e.g., 200A to 200A), using the same meter base and service entrance cable, some utilities allow the work to proceed without scheduling a full disconnect — relying on the main breaker for isolation. However, this varies by utility policy and jurisdiction. Always confirm with your specific utility before assuming you don't need to schedule a disconnect. When in doubt, schedule one — it's safer and eliminates any gray area.
