Is there any info out there on putting up suspended ceilings?I was also wanting to put some track lighting on it aswell. I've seen some good stuff in a shop where the tracks for the lighting were holding the ceiling tiles up aswell.

The on site guide mentions that all meter tails should be 25mm for tns. Every house (old) that I have been to has had 16mm tails and I have been changing them to 25mm. Is anybody else doing this?

right, that's that cleared up then! thanks for the replies.

dinbatwrote in an earlier mail: "547-03-03 - A supplementary bonding conductor connecting two extraneous-conductive-parts shall have a cross sectional area not less than 2.5 sq mm if sheathed or orherwise provided with mechanical protection or 4 sq mm if mechanical protection is not...

I am thinking about installing some master/slave dimmers-the touch type- not the pot type. Can the light be switched off from both dimmers, or does the slave dimmer just dim the light?

What type of bonding/earthing requirements are needed for a domestic boiler?

meter loops are 25mm. earth is 16mm

The MEM Memera board that has the spare way has rewireable fuse ways that are only rated up to 30A. The Memera board that has a fuse way up to 40A has a fuseway separate to the main bank of fuses, and mine is not that type.

10mm ft+e and the shower is 9.5kW.

A fuseboard I was looking at has a spare way, but it is not rated up to 40A, only 30A,so I was going to replace the board. I contacted a website and they told me that instead of replacing it I could add a shower unit (containing a 30mA RCD and a 40A MCB) if there was a separate main switch. The...

How does 6mm come about when the protective conductor to the exposed conductive parts would be say 1.0mm in the case of a light fitting? Or am I severely off the beaten track?

I thought 4mm was adequate for supplementary bonding if there was no mechanical protection in bathroom? p.s. thanks for the prompt replies.

A spark told me the other day that when he bonds out a bathroom, he takes all the supplementary bonding wires from extraneous/exposed parts to a earth connnector block local to the bathroom and then runs a 10mm earth cable from this to the earth bar in the installation consumer unit. I have...

I have recently noticed some 10a mcbs feeding lights in my house and 40a mcbs feeding sockets. Is this alright? I thought that they had to be 6a for lights and 40a for sockets.
