Thanks guys, I have tried to run the computer without the battery with no luck. Looks like I will have to try to strip it down. Any sites with detailed info on stripping this model?

Hi Guys, I have an Advent 7003, about 8 yrs old, which, for no apparent reason has died. It will not power up from either mains or internal battery. When the mains are connected the "charging" light flashes for a while and then stops. Any ideas what to try or look for?

Monty, As this is new section of cable I presume it will have RCD protection. Assuming you can squeeze the 3c+e through the tube, without any damage to the cable sheath, I can see no reason why it cannot be used as a "conduit " for the cable for the distance it is buried in the screed. If the...

Spot on Click-sure. The unit is mounted on an integral garage cavity wall and the insulation was blown into the cavity at some stage years ago. The property is @ 40yrs old and it was common practice to run cables in the cavity, I used to do it myself!

Is this what is meant by an "insulated " consumer unit? [net]

The current posts are 60' and about 30 yrs old. Although I am not sure of the height of the new ones, the "worst case" will be like for like (height) The old thorn 1500w single phase fittings have been replaced over the years with thorn mundial 2kw units which provide an adequate light. Four...

Thanks guys, I do not think there is any provision for cable support. I have seen cable with a built in support wire for pendant controls etc. and wondered about this type of cable for the column situation.

Hi guys, Is there a preferred type of cable for running up inside a floodlight column. The posts will be about 60' high and two 2kW (415v) fittings mounted on a cross arm at the top. Thanks for any guidance

If you are considering a consumer unit upgrade, why not make provision for the shower in the new unit? The secondary C/U could then be removed. Should you opt for an isolator the DNO would remove the sub board tails when they fit the switch.

I've come across this situation before and the "preferred arrangement" in our area is to bond at the meter position then bond the service as it enters each property, to its own consumer unit. (The situation is the same for the water.)

Thanks GaryMo, the Hagar write up indicates they should be ok.

I have used Wago connections several times and find them a sound fixing. To date I have not had any high resistance joints or any other problems. Has anyone used these as permanent joints, inaccessible for testing etc? (Reg 526.3) Could they be described as compression terminals ?

Thanks for that GaryMo, I need to check the book more often

Gary, are you sure the adiabatic can be used for sizing the main earth? I thought it was for protective conductors only

chri5, Are the neutrals from the outgoing side of the mainswitch designed to loop in and out of the first RCD, or can they be taken individually from the neutral bar on the MSw side?

Hi guys, I do not get involved with a lot of new build work so I would not know what the preferred practise is with installing socket/switch boxes under the plasterboard. The local builders are quite happy to have the boxes screwed directly to the blocks, but a new dry lining fella is making...

Under the boards!!

Hi folks. I wonder how many of you have found consumer units in the bathroom? This little surprise turned up when I went looking for a supply to a ceiling light. The light was still working when the 5A fuse was pulled and the other fuses in the small board were all 30A. This...

Hi guys, I am sure there must be some caravanners amongst the sparkies and other well informed of you out there. The regs indicate motor caravans (and caravans) should have overcurrent protection which disconnects all live conductors in their installations. All of the 'vans I have seen...

If the void is covered with a metal plate, thick enough to prevent the penetration of nails,screws etc, then the cables can be laid in this area. As already said though, any screw joints need to be accessible.
