You are permitted to have this changed to a 100 amp cut-out fuse, and an new meter, free of charge. When things changed to 230 volts... all that really got changed was the paperwork (as we just couldnt be doing with going round all the substations changing the transformer tappings to satisfy...

It is very dangerous to parallel subs. I would love to have a chat with the engineers who authorised that to happen!

A close lightning strike can induce current in the most weird and wonderful places. Its a bit overkill adding this into the regs but from an engineers point of view its common sense. Probably a one in a million chance but there was that girl in the papers who was in the shower when lightning...

Its part of the reason, but the main contributor was the current carrying capacity, Knowing what lighning is capable of I would always where possible use 6mm and if a bath is fitted, use a proper cast iron one, faraday cage, much safer.

Earthing is a very funny subject because its the only place electricity will be flowing under abnormal conditions, so you need to allow for absolutely every eventuality. Supplementary bonding also allows for equalisation of any potential difference in the event of a nearby lightning strike...

I would recommend bonding the joists, and using your own earth (making it TT) I would bring the feed via SWA into a CU on the brickwork (at a decent height) and have a main rcd switch - feed onto two 20 amp mcb's, one for each double socket and a 6 amp one (or 10 amp) via a switch for your...

Dont use the old cable, its a bit thin at only 1.0mm. Use the cable that (should have) come with your new oven and wire/plug it straight in.

this one will do the trick, its toroidal which is much better than electronic.. http://www.airlinktransformers.com/transformer/el150-single-output-12volt-toroidal-lighting-trans.asp

I just love the smell it gives off when that sort of thing happens, very inonised 'fresh air' sorta smell, bit like a very close lightning strike. Its addictive too!

Sorry to say but thats not true, Subs are only connected together in parallel for maintenance purposes. Thats where you see link boxes in the pavement (or sometimes feeder pillars) to enable links to be made. Then this allows backfeeding into the feeder pillar thats connected to the transformer...

This company makes really good quality transformers, including ones for lighting.. www.airlinktransformers.com

Thats contract engineers for you... not long before I got made redundant from the electricity board I saw exactly the same thing and had to step in. Showing them a schematic diagram was the worst bit as they didnt understand a thing!

No you can ask for an isolator before the meter. Makes it easier for routine meter changes too.

Sometimes you can get masterseal rcd (or normal) sockets very cheap on ebay, and brand new ;) hush hush to how the seller gets hold of them!

They could not be charged at all. To cover my ass im saying its not adviseable to do it but hey, this is britain and i live on a council estate ;)

just remember not to touch anything thats earthed, nor reach across to shake hands with his colleague working on the other line.... on a different phase ;) Yeah it can get very interesting.... especially working in substations where you have live 132,000 volt busbars a few feet away, what was...

oh no not another company moving their manufacturing to china???? this is getting silly. I like things that are proper british, hate fixing (or throwing away) chinese stuff. - - - - - - -

I was just going to say something very similar :P

Not like back in the days where electricity board people were treated with respect.... but all is not lost. When i finished my apprenticeship as an electrical fitter, my job was to work on, maintain, install and commission very high voltage equipment upto and including 132kV. Part of our job...

You could always ask the electricity company (DNO) that you require a double pole isolator to be fitted before the meter. Not commonly known one but they will do it for free as they have to provide you with this if requested. Then when the person arrives to do it, slip him an extra tenner for...
