    hi all

    As part of my project I have built a power supply to power up a heater, I am using a relay to switch the supply on and off when the heater needs it. However I have noticed that during on/off states the relay is drawing very high current and it is blowing the fuse up. I was wondering if there is anything that you would recommend to avoid this problem, i.e. adding capacitor at relay or something similar? I would really appreciate your help as I am on testing part and trying to get this project working before the deadline (27 Sept).

    With no information about the relay or a schematic of the circuit, we really can't offer any help.
    This is quite confusing - does the relay always draw current?
