    Magnetic Contactor Over/Under Voltage

    What voltage should be used in the UK for a magnetic contactor? 240V, 230V or 220V I know over voltage and under voltage can lead to the coils being burnt out over time. From the wall I am drawing in around 235V but when being used it drops around 225V-230V. Is it still wise to buy the 240V...

    Contactor not closing

    We have a contactor that controls backs of lights. The local switches are not working. If you kill the breaker and reinstate the contactor operates and lights come on. Once they time out the local switch should work. Is this the contactor not operating or faulty switches ?
