Hence, protective multiple earth. I can envisage a scenario where the earth bonding in multiple properties- if they were all on a common metallic water/gas system- could easily provide a better return path than the PME spikes.

When I worked for the electric board a 40 amp meter was "regarded" as being able to handle well in excess of it's rated current, and wasn't a safety issue. whether it measures accurately I don't know...

The DVLA have nowt to do with it, the police use the insurance database which the insurance companies repeatedly point out was never designed for such a purpose. And as for Gremlins attitude... times were, when I was a younger man, I'd challenge my peers to quantify their anti-police...

In short, make sure all the connections are tight. That said wire track is a pretty half a5sed setup at the best of times. An office I frequent has about 70 or so lights on a dozen or so tracks. I've replaced every lamp fitting and replaced half the cabling. And this is the "commercial"...

Your extension leads can handle 3 Kw, in the same way that your car can handle for example 7,000 RPM because thats where the red line is- you wouldn't drive for 8 hours like that though...

It's only the neutral which is solid linked between terminals 2-3 on the meter anyway, so makes no difference at all in terms of measurement. Current is measured on the phase- terminals 1 to 4. To be fair I'm surprised a meter fixer would be cleverer enough to think of doing that. Although...

Think you're back to front on that, voltage reduction increases lamp life. True, but the extension really should be on an RCD, and I doubt his leads will exceed... what is it 1,667 ohms? ~ technically poor practice, but in reality nothings gonna go wrong, I wouldn't go too silly on the...

def. metric, was retro fitted not so long ago. The council/LA housing still use it a fair bit for submain work round here so there are sparks that are tooled up to do it, I asked at my wholesalers for some numbers of such folk and have had nothing but brainache.

Not possible. '30's mansion block of weird, mostly concrete & hollow block construction. Easy option would be to replace it with SWA but that'd mean going through communal service hall (not a prob itself, but would have to liase with/inform the porters & building admin who in turn would...

Is there some secret masonic code I need to know when asking for someone to come put a pot on a bit of pyro for me? I've got a 16mm 3c in a flat that needs shortening and thought it wasn't worth buying the tools and doing something I've not touched in 10 years- I'll just get someone else...

There was an omicron rep in the wholesalers a few months ago with some all new LED GU10's and I must say the tech is improving, these had more of a warm glow that many people who dislike CFL's desire. If they can get the focused beams and dimming sorted you'd have something acceptable enough to...

Am I right in thinking you can backdate contributions? My 06/07 tax year was pretty good but the last was pretty poor (50% cap allw on van plus thousands to equip) I'm 30 and have no pension so should really start being serious about it... where would I go for independant, unbiased advice...

Same people. Assume you mean BT customer street. Also trades 4 you. I've tried everything from polite requests, pointing out they're breaking the telephone preference service rules, to unpleasantness, nothing makes them stop. I'm about to send a complaint to the BT complaints escalation team...

there's a difference between apportioning reverential status to a star and recognising that a licence thats slipped out-of-date by a few months might not be all that influential in the scheme of things. Consider this: My sister holds a full valid UK driving licence. She hasn't driven in...

tell him to "throw it through the house, don't bother clipping, leave plenty of slack as I'm threading it through after you gone" and he should oblige.

They think the apartment should be considered an installation in it's own right. TBH 99% of the time I'd agree without hesitation because a flat with it's own equipotential bonding is "safe" from what anyone does externally.

s'kay he only means to experiment. lol. reminds me of that ben elton skit. "for the last 15 years, I have been "experimenting" with lager..."

Seems about right I coax all my customers to have RCBO based boards, if you want the job cheaper ask about a dual RCD board, but bear in mind any fault will knock out half the circuits in the house, instead of an individual circuit.

It really depends if the driver is staring at his speedo having swallowed wholesale the "speed kills" propganda and doesn't see the kid, or if he's scanning the road and pavements for danger, sees the kid and pre-empts the situation by easing off and covering his brake. "hit me at 40 and...

Don't beat yourself up over it, but like the others say, put quotes in writing. it's not difficult- evan if you bang up some letterheads on a mates photocopier or printer and handwrite them. the better clientel will appreciate it, the chancers will know there's less scope for them to muck you...
