    Install new oven & induction hob to existing circuit

    Just had a look at OSG (amd3, havent got latest to hand) and you are correct for assessment of load on a final circuit to use that formula, can't get 15kW though...I get 13.8 to 14.4 depending on which voltage you prefer (!) thats for 2 appliances on same circuit.

    Motor control for chicken house

    Ok here is another go, I rectified at least one mistake. The coil of the open contactor is energised via NC aux contacts of closed contactor and vice-versa, is this not interlocking? The doors themselves are lightweight plywood being winched up or lowered down under gravity, I doubt they could...
