Hello,
I have a fused spur that I'm trying to power the boiler with a 3 amp fuse. It keeps blowing fuses so I checked the wiring to at the spur and replaced the switched spur. It still blowing. Its spurred from upstairs ring so I isolated and tested the wires with a muli meter. The second time I did this the fuse blew when I just connected my multumeter to check volts between neutral and earth. Any ideas on what could cause this? Its ok with a 13amp fuse but there is obviously something wrong so will not use until sorted.
Thanks......
