    I have super powers! I took a two hour nap today. I have never had a two hour nap. Normally it is fifteen minutes and I am raring to go.

    oh the drama ----- im with SJ on this one - it will be interesting to see next months electric bill,

    But - on a side note - I knew a guy who had the exact same thing happen and the thing is is he did end up flying afterwords - it was amazing, he said the secret was that you have to have faith/conviction --- just jump and point your chin directly at the ground and you will fly because of your new superpowers,

    so good luck to u BF - let us know how it turns out and take some pictures too... god bless...

    Just so you all know. That was a joke about my friend in the shop. Even I wouldn't do that.

    you want to watch out for fake chinese mcbs as well

    no trip mechanisms inside ..they are just an on/off switch

    JL.................

    I invited a friend of mine over this morning. We took coffee up to the shop and I went around the shop asking him various questions about my different machines. In the course of answering my questions he always touched the machines. He is still alive so I guess there was no current on them.

    Anyone on here want to stop by for a visit?

    "Shorting across" the breaker only tests if it will open on an overload. That says nothing about the ability to trip for an earth fault. They are far different mechanisms.

    An earth fault is (as I said before) leakage from the energized wiring to earth, from any cause. That may include you in the circuit, or not. Wet wiring can cause the earth fault detector (GFCI in the 'States) to open.

    EVERY GFCI that I am aware of has a test button, that applies a resistance to earth sufficient to cause the minimum required trip current. If the GFCI does not open for that test button, it is bad, and should be replaced.

    Question (1) is what KIND of earth fault breaker do you have?

    The type which is for protection of people has a very low trip current, about 3.5 to 5 thousandths of an ampere (0.0035 to 0.005 ampere).

    The type which is for protecting equipment requires 10X more current, and offers no protection to peiople.

    Question (2) is what were you doing when you got "zapped"? Where were your hands touching the equipment?

    Because , as mentioned, the GFCI type device does no good if you are "across the mains", because then you are drawing current just like a legitimate "load".


    Evan's picture:

    Curiously, although I would not do it for any amount of money that you can name, dropping a live extension cord into THAT SPECIFIC KIND OF POOL is not necessarily instant death.....

    It is all about the path of the current.

    THAT particular pool is all plastic, and current can only go between the wires....it is (at least theoretically) insulated from earth ground. those at a distance will not have any effect unless they step OUT of the pool and have contact with water AND earth ground at the same time. (if there is some grounded object that we can't see, that's different)

    In a normal pool, with concrete sides, and grounded inlet and outlet pipes, the current CAN AND WILL pass from the extension cord to whatever grounded item exists, perhaps the pipes, or directly through saturated concrete. THAT is extremely dangerous, and explains the whole pool (or more especially, bathtub) and electricity deal.....

    Is that the same as slightly pregnant ?

    would you please give us an overview of the electrical setup before more of the armchair electricians speak up?
    This is how it works. Nothing special about it.

    The electrician can not come today. I tested the ground fault breaker by shorting across the leads and it triped fine. I put my cable inside last night for it to dry. This morning I had no electricity on the frame. I tested it with one of those screwdrivers that light up. Nothing. So I touched the frame with my finger. Nothing.

    I had a tough night but now I am feeling better and not so much swelling. When the electrician comes I will have him change the breaker even though it seems to be working correctly.

    Here in the States, (well, most of them) they still think the average citizen is capable of electricity.

    I built and wired two houses, my own, requiring only a desultory inspection by questionable public officials. (I have seen some pretty shabby work elsewhere approved by the same official). I was also self-employed for almost 20 years, wiring control panels and machine tools, all legal, all without benefit of license or certificate. Only got minor zapped twice in the process.

    That is not to say that I have anything against the licensed electrician, and BF is wise to have one in to look at his situation.

    Extension leads are included.

    Testing is mandatory and annual or after a machine or toll has been repaired as ready for use.

    Having or using non-tagged or "Do Not Use" machines is best described as liable to prosecution.

    Not knowing or not conforming is no defence.
    Tiffie is right, Australian's are total pansies when it comes to mains electricity... I cannot even connect 3 coloured coded wires to a plug.. If you do do that and have not done the required four years mandatory training, they will send you to jail...

    That depends on the type of shop that they are in , I dont have to tag any that I am using for test as long as they do not leave the workshop, and are only used under strictly controlled conditions , eg no visitors or lending to anyone .
    I even have what is referred to as death leads again only to be used in shop for testing repaired equipment ,there is an earth leakage on each circuit and the main box is also fitted with the compulsory unit which I specified to be only 30ma trip current .
    I think it is far better to get annoying trips than be carted off in a box.

    However all equipment that even may go outside for any work purpose has to be regularly tested and tagged.
    I asked before getting into trouble with the electrical authorities.
