mmm industrial stuff is much more fun, i do enjoy design and site management, but odd ball PLC faults are such fun to solve.

Ali and copper cables can be joined without a problem as long as the joint is covered with a compound with prevents any electrolytic corrosion, ali cables will burn back during a fault, I repaired a 300mm SWA a few months ago it had been damaged during excavition work and re-buried almost 4 feet...

There is a mine in the corsham / bath area which was used during WW2 as a arms factory. the HV switch rooms had a water sprinkler fire system intsalled. The kit was still in use untill about 15 years ago when the sprinklers went off. im gland i was not in that switch room at the time....

I recon your house has its own earth electrode/stake and no earth from the suppliers, check that the stake is connected. the only other thing is the italians might not reference there supplies so then there will be no connection from neutral to earth.

some supply authoritys no not charge to replace seals and are happy to do it if u changed a board, i've got a SWEB seal crimp tool and some of there anti tamper tape so its not an issue for me!

u should be able to cut it with a jigsaw but it needs to be one with speed control and use a fine tooth blade and cut it from the back or use a reverse cut blade (designed for laminates), just take it slow. a angle grinder will often make a neater cut but its difficult to be precise.

get the installation inspected and tested and the defects repaired! sorry but its the best way

best one i've even seen was Winsor Coles from the HSE always had a plug top with a solid brass pin rather than a fuse! his farmer friend gave it to him!!!

I'd go for SWA its much stronger than any other cable out there

i'll happly install it if it is necessary, but very rarely do, having said that i dont install alot of cable these days. " There is nothing on the market that is fire proof except MICC" as i said special installations. i see so many badly installed cables of all types. on a inspection of a...

tell him to replace it! it should clean off glass& metal but it will take years to fade away from on the wood

interesting idea, im not sure what the yanks use as qualifications. I've seen engineers jobs advertised and a ONC or HNC is considered highly state side. They tend to use parially skilled people doing individual jobs and still love conduit! I think they are beginning to change there idears...

we should look at europe they use rigid round cable a million times better for the majority of installations than MI SWA T+E etc sorry but MI is so last century :lol: it costs a futune to install i can see your the resons for your arguements but those are special installations, if the...

Selection and errection! i all depends on the environment it is placed, T+E will be suitable in some environments SWA in others SWA with a 6mm steel capping will be required in others, MICC is only suitable if there is no vibration perfect cable routes etc, i've inspected countless...

Thinking about this i did replace one of these boards which had blown up in a big way, it was very close to a 2MVA transformer and had a 250A incomer so it was hardly supprising it when bang when the roof leaked onto it. i have never seen another fail and have seen every other make have various...

i've seen alot of these boards they where available until the early ninetys as far as im aware, i would say unless they are the late design which was IP2X with the cover removed i would bin them.

its distilled water so bottle it and sell it to a garage! The water issue is one reason i tell people to fit a static rather than portable unit. its also why there is lots of little puddles beside petrol pumps in the summer

MTX75 from a late sierra or granny but u need a specail bell housing

I've seen them fitted but i really think its a dangerous idea, the cheapest and safest option is to find some later rims which return to imperial sizes, BMW rims fit i beleave to?

There is several options, i would extend the cables and fit the transformers above the water line. i would expect the transformers will be ok if fitted in a resin sealed joint kit the water will keep them cool but one big enough is going to get expensive. simple primitive solutions, fit the...
