    Pay as you go meter change

    Update. Customer phone supplier and the supplier will not change to a payg standard meter. Seems harsh but they push big on smart meters now. I can see this unit eventually giving up the ghost and then the customer will be fitted with a smart meter imo. Thanks for input

    Ramp up down switch single phase motor

    Thanks lucien nice to hear a full and informative reply. The mechanics said there was smoke coming from the switch and the little transformer looks worse for wear, what would this transformer do? Yes its a very old hydrolic ramp with no safety locks its really old, Btw no valve to drop down

    Ramp up down switch single phase motor
