I was under the impression that you need one master box with fuses for each sub-box. The master box should have the Amp rating for the entire house. How many kilowatts do you use in a year? |

Evenbob Member since: Oct 24, 2012 Threads: 146 Posts: 25010 | The pic is of the master box. The side boxes have 2 fuses each and can be shut off individually. KWH a year? Not many, I don't run much here. Probably 500-600 a month. If you take a risk, you may lose. If you never take a risk, you will always lose. |

This is the 200 amp box in the barn. If you take a risk, you may lose. If you never take a risk, you will always lose. |

The small panels are rated for 100 Amps but you can put a smaller main breaker in them of 60 or 70 amps (or less) for a non residential application. The Canadian electrical code now requires a 100 Amp minimum service for a residential application I am not familar with the American code. "but if you make yourselves sheep, the wolves will eat you."

Some of those huge factories are programmed so that robots "jiggle" their pathways a tiny bit so as to not wear the floor in any particular pattern. |

In a perfect world. I saw the video Musk put out. But when the vehicle gets older and the bolts and other fittings get corroded it will not work so smooth. And do not underestimate the space needed for all the batteries to be swapped. The President is a fink. |

NEC 230.79(C) does require a minimum of 100 Amp, but I don't know if that means older homes must be upgraded. Obviously Evenbob's home insurers inspect his home and have not denied him insurance. |

Never had one in here, they never ask about anything. Have had the same agent for 25 years. If you take a risk, you may lose. If you never take a risk, you will always lose. |

I have written reports on several older homes in which the insurer had wanted an upgrade to 100 Amps. If I demonstrated that the wiring was basically unchanged from it's original installation and the Canadian Electrical Code demand for the premise came in under the main breaker rating (typically 70A in older homes) then the home still met the current code requirements and the insurer would allow them to remain. In the picture EB posted it looks like the fuses are all green which would mean they are 30 A and the wiring connected to them is not sized for 30 A so he should hope he doesn't get an inspection. It is a dangerous situtation that an electrician would have to report/fix to avoid liability. "but if you make yourselves sheep, the wolves will eat you." Benjamin Franklin |

The same thing at my parent's house. All the fuzes were 30 Amps, which means they were installed before 1977. I insisted that they should replace them with 15 Amp fuzes, which bugs my parents since they burn out sometimes. The home was inspected at least five times, and the inspectors never noticed. I get crap for creating problems, but they walk like tortoises. They are not going to outrun a fire in the walls.
Evenbob should put his dryer in the barn, and switch his house to solar cells. He should be able to run his lights and his computer. An average of 700W device running 24/7 is 511kWh per month. |
