    Is electric panel dangerous?

    Electrician saw white on breakers (see pic) and says I must replace whole panel with a larger one because it’s overloaded and dangerous. Does this sound right?

    Sub Panel Question - Panel Size/Breaker Size

    I am looking to add an 80 amp sub panel for my detached wood shop. The smallest sub panel I can find has a 100 amp main breaker in the panel. Would it be ok to use this panel, and just connect to an 80 amp breaker in the main panel? Thank you!

    Using solar panel DC output to feed immersion heater?

    Just an idle thought - has anyone any experience of using the DC output of solar panels to directly feed an immersion heater, to avoid the expense and losses associated with an inverter?

    Advice on conflict between generator interlock kit and subpanel requirements (Siemens Panel)

    I recently had my 50yr old 100A main panel replaced with a 200A Siemens panel (MC2040B1200EFC). It is the incarnation with the 200A main breaker at the bottom (earlier versions were center fed which would have alleviated my problem). At the same time I had the electrician add a 50A inlet for a...
