Garage Earthing system

[william7900]

Hi friends,

I have been reading threads concerning garage earthing arrangements. Advice was given to extend the earth from the house to the garage. Please may I comment that this is a dangerous practice because if by accident someone went through the SWA cable with the mower etc, the result would be catastrophic, due to the fact that in the garden you will be in contact with the earth and a perfect conductor for electricity and receive a severe shock. The earthing system for a garage should always be TT, using earth rods and trying to achieve a resistance of 200 ohms. You may have to use more that 1 earth rod to acheive this. The garage unit should always be RCD protected.

This is why on building sites all the equipment is supplied by transformers which gives a separated environment and no earth is used for safety. Hope this helps.

Regards,

Bill

I think he's taking the pi**!

Yep! Mental note: never move to Luton, the electrics are most probably dodgy.

Another big myth is that the DNO forbid the earth of a TNCS to be exported. What a load of crap. They don't care.

It's unreal that there are these people, still around out there!! These people will happily go around making TT systems willy nilly, probably using those 3/8'' 1.2 m excuse of ground rods, that can very easily leave an installation void of any earthing during adverse weather/temperature conditions. Because they know no different, they will ditch a superior earthing system and will spurt out this total nonsense about ''it is forbidden'' to export PME!! who the hell told you that?? Well....how about ''Extending the equipotential zone then?? I take it, you then think that an outside socket outlet on a PME system is also banned??


William, the only confusion in what you have posted is yours, as you obviously have no idea what your saying here. You have been wrong in just about everything you have posted on this subject. Please go and read the Sticky on this subject, then come back here and try and tell us that were all wrong and that your right!!

The scary thing is, that i don't think he is taking the Pi**, he's actually being serious in his beliefs!!!

Guys,

The suppliers do not reccommend it as a matter of safety. This is why we have regulations to protect us in that 1 in a million chance of being injured. Unfortunately not all of us wish to adhere to them until it affects us. Just as a matter of interest the part P of the building regulations came about due an MPs daughter being injured by an electrical fault.

Keep safe guys.

Regards,

Bill

Bill that last reply is vague and unhelpful to your pointless arguement. Firstly you said the DNO does not allowed us to export a PME earth now you say they don't recommend it. Which is it? Which reg are you talking about. There have been a few others that have said about regs but could not find this hidden reg to back up their argument. You are wrong plain and simple. Just give up with argument.

Take a look at this Bill.

Sorry for the repetition - Just spotted someone further back has already pointed this document out.

She wasn't injured, she was killed. However, her death came a long time after the consultation process began which resulted in Part P. Merely a tragic coincidence.

Stop, and think about what your saying. Based on your electrical knowledge on how earthing/bonding systems work you will come to the same conclusion as the vast majority here. Your basing your reasoning at the moment, on myths and scaremongery that originated from those that opposed the introduction of PME in any form for general distribution.

As i stated in earlier posts, you have been wrong in just about everything you have posted on this subject to date. You are also very wrong in the ''one in a million'' statement, the chances of experiencing let alone being injured, is far far greater than that!!

The only restrictions to the use of a PME system are well founded, but do NOT include extending such a system to a domestic outbuilding, shed, or garage!!
