    Well, lets see....if it feeds overhead, the power co eithers cuts it at the pole i.e. the individual service connection. Or at the house depending on what needs to be done. If the service is UG, it will either be disconnected in the transformer if it feeds from one, or a secondary enclosure, again only removing the service to the single customer.

    The utility I work for doesnt allow an electrician to bypass the meter. You call the power company, a crew shows up does the disconnect, you do your work, the crew returns heats it back up. Residential, $212 ripoff that the regulators allowed. Commercial 3 phase, depends.......

    Howdy i cringed when the Electrician grabbed the live wires and strapping cable with a bare hand. Kids watch this show so shame on TOH...... Safety glasses are always referred to but is that the extend of their idea of safety... Boneheads! This needs to be addressed on a future program to warn kids to never touch these lines- including tall middle aged kids. Sudden death not addressed is sure more nasty then putting an eye out. otherwise. Shame Shame Shame.


    Lineman's gloves and caution to never grab these energized lines would of been the professional first heads up!
    Has that electrician never seen a short caused by worn insulation on wire? Man turn the channel....

    Every place I have seen, for above ground service there is a fused switch on the pole. Takes about 30 seconds. VS if 2 of the wires had touched you would of had an arc flash that would have at least knocked both of them off the ladders. Melted all the exposed synthetic cloth. At least second degree burns most likely some time off work with burned hands.

    The fused switch controls power to the transformer, in some places one transformer feeds multiple homes.

    The switch for our utility feed is further upstream ( down the lane ) ---- so without knocking power out for about a dozen homes ---- how else would you do it ?

    The fused switch is known as a cut-out box, it generally fuses transformers or primary branch circuits. Cut-boxes are not used to disconnect individual service connections.

    Ummm, yes I have a masters license. I was curious to how power was cut on a single residence when a transformer tap might feed multiple homes in different areas of the country and with different power suppliers regulations...... It goes beyond the NEC and is not really covered in NFPA-70E.

    I would say that a lateral cut to the home is no more safe either by an electrical contractor or the "Power Company" as long as I follow 70E.

    I would also say that fault current at a residence is seldom more than 10k and arc flash is minimal.
