    Default Electric Hazard

    Question - you have a flooding condition, pipe feezes and dumps water on and around sub-panels and entrance panels in a commercial. Floors has 2 inches of water accumulated. Meters are inside on same wall as entrance panel with no obvious disconnect point other than having Utility disco at pole. What do you do?

    Call the power company and have them disconnect at the pole.

    This kind of fits into the "DUH" category.

    Default Yes! - call the utility

    Most commercial establishments have "Shunt" type meters. This means there are calibrated resistance bars across the meter socket, so even if you pull the meter the power is still on. Also many use delta or wye connected 3 phase supply which might even be worse if a FF entered the water to attempt any type of activity.

    FIREFIGHTERS SHOULD NOT PULL ANY KIND OF ELECTRICAL METER!!!!


    The electrical meter measures the usage of electricity, like the speedometer/odometer in a car lets you know how fast you are going and how many miles you have traveled.

    From a post made on 9/17/2006 by SPFDRum

    CaptainGonzo is correct. (anyone surprised? ) Especially if you are dealing with a newer developed area, or an area that has had it's electrical services upgraded.
    Back in the day, meters where place in series with the service. All power passes though the meter and continued. With this type of meter and socket, it was possible to remove the meter and kill power down stream. Even then it was very hazardous. If you where drawing current at the time you tried to yank the meter, the possibility of arcing from the lugs to the socket to a ground was a real possibility. This, to put it mildly, is bad.
    New meters are place in parallel to the service, and with the electronics installed, there is no need to shunt all the current through. One of the ways to ID this type is if it has a handle that releases the meter from the socket. But if you look close, you will see it doesn't interupt power.
    Unless you are a trained electrician with line experiance, all the proper equipment, a department SOP saying it's OK, permission from the power provider, and a really good reason, leave them alone and call your power company.

    I know it seems basic I was just wondering if anyone had any other ideas or if there was another option then having utility disco. The utility takes forever in our area.

    We do the same . It also can take a very long time for the utility guys to show for something as basic as this. An engine stays at the scene until arrival of electric company. 20 minutes or 2 hours they wait until relieved by a responsible person.

    I really hope the guy or gal wearing the red (or white) helmet (you don't get to ride in the right front seat for no reason) would figure this out.
