Thanks Bernard, I can see this is the belt and braces approach, in your experience, is this custom and practice for this kind of outside installation? If I install a rod, might I also then be saddled with the future costs of maintenance and testing of the earth rod? I've heard that they are not...

Hi folks, I have an upstairs cupboard with a false floor that can be removed to reveal a large void where the alcove in the kitchen has a lower ceiling due to some steels that support the floor joists above. This seems like an ideal place as a install some electrical bits and bobs to keep...

I experimented a bit and it seems it is much easier to re-thread through 25mm oval conduit than 20mm round anyway, and almost half the chase required, only about 12mm to completely recess the oval in the block(to ease any future order from on high to replaster). The 35mm back boxes are in the...

Thanks for the feedback folks, after all your advice, I've used metal conduit with plastic adapters on the end without adding bonding to the box. I think I was over thinking it! Thanks again.

Thanks for all your feedback folks, I'm going to read up on the lost neutral problem to try to understand it. I was thinking that the earth was there to protect against faults and that a 10mm bonding was required to make sure of a low resistance path to trip the fuse. I was going to use...

Thanks for your fast reply John, would a steel conduit back to the earthed internal back box count as a low resistance back to earth? What are my choices if that low resistance to earth makes it count as an extraneous metal part? Change the steel conduit for plastic? Is plastic conduit allowed...

I have an outside metal box housing an ip rated double gang socket, which isn't earth bonded. Is this a problem? Whilst I am chasing walls to add network and TV cables, I was going to add a network connection and maybe an alarm cable to this box(with another network connection on the inside)...

Hi Folks, thanks for all your brilliant replies. I've decided to chase only 12mm out of the brick and put the wires in oval conduit rather than round. I've been reading up on these 'lounge plates' for sat\TV\FM and it seems they only need 2 lengths of coax not the 4 thought was needed and was...

I just read JohnW's reply, so I think we are ok with even the deep back boxes! I might have a closer look at the long row of face plates in the kitchen though! As far as the cable chases are concerned, I may have to abandon the prospect of easy future replacement via plastic conduit and just...

Thanks Guys, I had thought about the backbox depth(in relations to the chasing rule), especially where there is a row of double gangs, and then decided there was no way round it, other than surface mount(shrieks from her in doors) The internal blocks are only 50mm deep cinder\clinker type...

33% of 50mm doesn't give me much wiggle room to get the conduit flush with the brick to allow for boarding out in the future when the rest of the plaster fails. I had hoped that the rule might be different for none load bearing walls that are supported from behind by another wall! Either way...

Hiya Folks I'm planning on chasing a channel in a wall for cables for a 'lounge plate' e.g. TV, FM, SAT, network, phone. I'd like to put these in in conduit, it will probably have to be 25mm round. What is the maximum depth I can chase the wall out vertically? I've read that the maximum...

I did notice that there seemed to be companies online performing this kind of draft proofing, so I thought it would be OK, but then after a bit more thought I was worried about damp, but there doesn't seem to be any, hard to assess the effect of blocking off the draft, and I hopefully wouldn't...

Thanks John, speaking of which, I'm planning on pluging the hurricane coming through the joist ends, with a sheet of plasterboard and foam, I can't see any downside and I noticed some similar advice on the house builders federation website. I think that draft is just unwanted ventilation?

So worth doing for the alarm then. The cameras are through the eves so not so difficult to get at in future as downstairs alarm sensors and keypads etc.
