The electricians came to turn off the power on the second floor (the floor we're renovating). There were two circuit panels on the second floor. One in the staff kitchen, which did not power the kitchen, but instead ran a 220 line downstairs to an A/C unit and another 220 line to a disconnected gas heater unit (which is for sale, see the next post). The larger circuit panel ran four 220 lines downstairs (A/C units and machinery) as well as powering the staff kitchen - the kitchen is not part of the renovation and needs to be live throughout the project. So the job wasn't simply disconnecting all of the circuits, we had to follow each line to see if it was needed (kitchen, A/C unit, machinery, etc) and keep it live if it was while removing any inline junction boxes, then disconnect the nonessential lines for demo. I would have done this myself, but the job was more complicated than it looked and I think we got our money worth. (Shout out: H & R Electric, Pawtucket - highly recommended)
