There is a big difference between "Electricity at Work" and "Electricity at Home" – not the electricity it's self, obviously it is the same, although at work or in the larger homes there may well be 3 phase, which immediately increases the risk and danger to the untrained. But . . .the way in which electricity is operated and used is very different, for example, in the work place any 'work' on or near electrical apparatus MUST be covered by a 'safe system of work' requiring an 'isolation and locking off' procedure, and issue of a safety document to record the actions taken to prevent inadvertent electrocution to the person sticking their fingers on the conductors !
How many of us would do something like this at home, when you're next balanced on a pair of steps wiring in another 6ft tube in your workshop, ask yourself could your shmbo wander in and turn on the light and 'zap' you because you have only switched it off at the light switch rather than isolating it correctly ?
I would think that prospect wouldn't even cross our minds, or what about the four different things plugged into one 13A socket (I've seen the pictures on here of folks workshop set-ups)
How many Lathes and Milling machines are plugged in with a 3 pin 13A plug ? when it would be much better if they were connected to a 'dedicated fused spur' protected by a MCB of the correct rating ?
There are, I'm sure many of us who undertake 'home electrical work' and I suspect that a lot is not even close to meeting the requirements of the Institute of Electrical Engineers 17th edition Regulations.
If there are folk on here who can offer qualified and SAFE advice, then in my mind that has to be a good thing, and if the advice offered is dubious, then knowing how forums work, it will be corrected PDQ by someone who knows better !
