So 16mm of earth cable from the consumer unit to the outside box. Are you saying then that a time delayed main switch in the consumer unit is not necessary and a 100A main switch would be fine. Why do just the whole of the sockets in the house need rcd protection and not the lights. I take...

What would you suggest i do now then? Does that mean that i have a valid earthing system in place at presant, if not would it cost me to get the rec in to undertake this work?

Right Sparkies have a look at these then. Give me your thoughts as discussed in previous posts above. PME or TT That green sticker states PME system. The block above says Henley on it and states 100A TypeII B. As you can see i've just laid some new drains etc.

Oh right. How do i actually find out. The earth is coming out of the consumer unit to the rod. the big block states PME. Would some pictures help?

How thick is the shower cable, what approx is the cable length and what KW is the elctric shower? Has the RCD got a test facility like mine?

As many will be aware, my earthing set-up is a TT earth system. This evening i opened the met box on the outside of my house soley for educational purposes. It looked very neat. I do however have a couple of questions. 1) There is a block before the meter, which states PME on it (series...

No... no joy either. There isn't a picture in the html.

Does it cost for them to fit an isolator or is this part of the service? what is the rough going rate for the met if needed to fit an isolator?

ermmm. Ban being a Professional? If you are talking about the fact that he is an elctrician, does this mere title constitute to somebody being a professional? This could be one interesting debate! Is having a professional ethic essential to the existence of a professional, and in...

would like to see the pic if you manage to get it.

£1600 £400 notes a day. If it's a council £2000 or where they are using public money... Just joking...

No plug it's not an electric combi boiler. I was getting confused when it was stating large KW as energy transfer not thinking that this didn't mean electrical energy transfer. It is a Gas bolier

Thanks gang, that's cleared things up for me....

ok so can you teach me how to calculate this aspect?

Conduit won't help. You will need some appropriate outdoor cable like SWA and this will need to be terminated appropriatly. Think of the elements and the fact that it is electric. wire + Water = :cry:

yes... point noted it's about thinking ahead, for example using a 2 way switch instead of a one just in case one day... you never know

Ban, c'mon that was only a point that you've made in relation to a point that i've made in my post. You haven't advised on the core of the thread which was the issue of the SFCU and the amp required. Your 28kw 28,000/240 = 116 Amps. How is that wired up then, i am not aware that they do fuses...

so if lights are single phase and you only need to connect the live and neutral what do you do with the earth, strip it back or what?

I disagree, this topic has been covered before. If you are coming to do my electrics then i would like to be fairly assured that you can answer electrical questions thrown at you from any direction and would hope that you would be competent to know the answer. Remeber it's ok using a...

Hi all, I've been looking around at combi boilers of late and have stumbked across something that i need answering. for example a combi boiler on B&Q's web site states that it is 21KW. Now to me that seems quite high. I then thought that you would need to get power to this and that way...
