It should not be hot on the bus, but always check with your multimeter first before doing anything else. Usually this happens as the house gets older and older. Electrical control panels are designed and used to control mechanical equipment. To do that, equipment must be obtained and mounted on a back panel and after that wired and coordinated into the machine. IMPORTANT   If you were in such a situation where you were allowed to turn off the main power, the electricity is flowing through one side of the main breaker. y Two-way switch: It is used to divert the flow of current to either of two directions. As already mentioned, in a lot of areas of the country the ground and neutral bar are all attched on the same bus (or bar). Start with the basics and build from there. When finished with electrical components, always clean the area. 3.1. These panels don't have dedicated disconnects. 2.3 Recognized components shall be used within their electrical ratings.
