  1. Today, I had to sign for someone because he needed to re-get electricity in
    his premises to lent them.The new greek internal installation code says that
    it is compulsory to install a GFCI breaker in the service panel.So I had
    to.But the guy got really mad at me, probably because he thought it would be
    too expensive, and said he would find another electician.And I needed 6
    hours on the PC, autocad, to make the damned plan!At least, after a lot of
    thinking, he hired me, fortunately, and the union got 67 euro,part of which
    at the end of the year will be mine.In EU we don't have GFCI outlets.Only
  2. BTW,GFCIs are called here RCCBs-Residual Current Circuit Breaker.The term in
    greek would be literally greek to you.They can be wired either way-load up
    and supply down or the other way.

    So what are RCD protected socket outlets ?

  4. In the UK we have both types.
    Our GFCI outlets are expensive though, more expensive than
    a single GFCI panel breaker, which can cover many outlets.

    You can buy plug-in GFCI's here easily, and they're cheap.

    That's amazing on this side of the pond you could buy 3-5 GFCI receptacles
    for the price of one GFCI breaker. And the GFCI outlets can protect
    downstream non-GFCI receptacles.

    His last name must be Tzighounis, eh? Parata ton!
  7. In the UK, GFCI outlets don't have any connection for downstream
    protected outlets. It wouldn't make much sense, as our outlets are
    normally connected in a ring circuit anyway.

    So if you want to add an outlet you have to loop both sides of the "ring"
    to the new outlet?

    Seens wasteful to me.

    Note that in the US, better quality GFCI (still less that $10 each) have
    ways of chaining with the line or load side. The electrician only has to
    strip 1/2" of the wire, poke it in the hole, and tighten the screw.

    You can add an extra outlet by tapping off the ring, but usually as
    the ring is fused at 32amps its not wasteful, but safer to take both
    sides of the ring to every socket.

  11. You don't have to. You can create spurs off the ring.
    Generally, a newly installed ring won't have any spurs,
    but later additions are often done that way.

    And on the basis that two cables take up little more
    space than one, rather than taking a spur, you can extend
    the ring after dividing it at the point that would otherwise have been
    the spur take-off. But be careful, just as there are limitations on
    the number of spurs, there are also limitations as to the maximum
    size of a ring.
