My transmissions trips the fuse switch in the main fuse box. Background. I went QRT some 31 years ago and have now returned to the hobby. My original HF rig was a Trio 599 Custom Special twins (M). I had a vertical outside the house and I had a 10, 15 and 20m wire trap dipole inside the roof space. I now have a Yaesu FT991A transceiver. I do not use the internal ATU but purchased an LDG ATU. For a short while I have been operating with what I believe t9 be the old wire trap dipole which unfortunately had been disturbed when loft insulation material was installed. A short while ago that trap dipole was rehung correctly. My shower is in the bathroom on the upper floor and the fuse box is on the ground floor under the stairs. The shower is fed via the correct 250VAC cable up to the roof and down to just outside the shower room to an on-off switch. The cable feeds into the electric shower through plasterboard into the shower cubicle. Each time I tune up or just transmit the fuse in the fuse box downstairs trips and power is shut off and hence the shower will not operate. Has anybody encountered this problem and solved it?
