Stop first if
- Anyone assumes the main off means the panel is dead.Stop. Line terminals stay live until the utility disconnects upstream.
- A panel is open with crews nearby.Keep crews clear until a qualified person closes it or it is de-energized upstream.
- Equipment is scorched.Leave the dead-front on, keep clear and call a licensed electrician.
- The service has current-transformer metering.Never open the secondary. Leave it to the utility or a trained meter technician.

Ask on the call
5Homeowner? These are the questions a good technician will ask you. Having the answers ready makes the first visit count.
- What work is being asked for, and why?
- Is the cover on right now?
- Is there a meter or disconnect in a separate enclosure?
- Are there several disconnects for this service?
- Is this a house, or a larger building with metering cabinets?

- A licensed electrician arranges any utility disconnect, then confirms absence of voltage.
- Keep the cover on, or de-energize upstream, while other crews work nearby.
- A qualified person stands to the side when operating a disconnect on faulted equipment.
- Refuse any backfeed plan and record the refusal.
