Re: Question For Judd
Had a look, the spur is on a dedicated 16 amp MCB, the big issue was the fitting of a 1KW electric heater, that will be used infrequently, you answered the question in consumption as 3kw on this 16 amp spur, I am sure the remaining 2kw will be well within tolerance for computer, TV etc etc. As far as the earth loss is concerned, @ 20 metres, there is a rod set to earth by the Garage Door, maybe to service some antiquated and decommissioned unit on the garage wall, I could strap and additional earth connection here.Re: Question For Judd
Does your incoming service cable include an earth? Most now do but in the old days you had to make do with a spike (earth-rod). Don't use that old rod as an earth. If your service cable includes an earth, the difference in earth values between the supply earth and the old rod could cause problems with parallel earth paths under fault conditions. Best not to use that rod at all if you have a service cable earth, if you have, just disconnect any earth-wires going to it and run some insulation tape round any exposed part of the rod. Make Sure of your earthing arrangements before you do this. If your supply is what they call a PME, there will be a label on the incoming fuse telling you.Re: Question For Judd
No, that unit was cropped a long while ago, when the electrician fitted the new consumer unit, I made available access to the houses cabling and extended the spike that provided the original earth connection, if I remember right I asked the geezer if another earth could be employed and he said that the earth for the consumer unit could only come from one source, and what I provided was sufficient, that is why, remotely, I would not introduce another earth point without asking.Re: Question For Judd
Re: Question For Judd
Its coming back to me now Judd, when I extended the front of the house, there was a spike, which was wrapped and cemented in with the footings. When the new Consumer unit was fitted, I was told a better earth was required so, not wanting to cause upheaval inside the house, I put a strap on the water supply pipe, and ran the earth cable through conduit under the block paviors, around the outside of the house I left the installation open so the electrician could satisfy himself that it had been done in accordance with regulation, and saved me a few quid in labour, same went for giving him access to the cables, the ceiling was completely open, and the cables ran up the wall from below where the central heating boiler is now, he just unshipped them from the old unit, rerouted them through the open ceiling, and down the wall to the present unit. The supply tails were extended to reach the new position of the unit, and run upwards to each side of the unit.
