GFCI outlets
Is it ok to make each outle tin a GFCI circuit have its own GFCI outlet? When my house was built, one GFCI outlet in one bathroom protects the outlets in three bathrooms, so If it trips, the other outlets go out. I assume there is not a disadvantage other than cost to have each bathroom have its own GFCI outlet even if it is on the same circuit?

I know you didn't ask, but I'll toss this out anyway. You will need to move the wires on the first GFCI off of the Load terminals and either attach them to the Line terminals or in some other manner ensure that they are connected to the source hot and neutral. Basically, what you need to do is make sure that each downstream receptacle is wired correctly so that the previous GFCI doesn't impact it when it trips. Of course, this leads to the question of why is the first GFCI tripping. I can't recall the last time a bathroom CGFI tripped in my house. My garage ones have tripped when the holiday lights got wet or something similar, but my bathroom GFCI's never trip. |

AFAIK, you're not supposed to have a GFCI on a circuit that already has a GFCI. So, if I understand it correctly, what you'd like to have is one GFCI in each bathroom. That GFCI in turn would protect the other downstream receptacles in that bathroom. That would be easy to do if you were wiring from scratch. To do it now, you have to get a non GFCI circuit into the second bathroom. I can see two ways to do that. 1 - Run a new circuit. 2 - Find where the first receptacle in the second bathroom is tied into the GFCI chain in the first bathroom. Have each receptacle in the first bathroom have it's own GFCI receptacle, ie don't use the load side of any of them, up until where the branch point is going to bath 2. Just pass the line side through to each receptacle up to the point that the second bathroom is connected. If there are other outlets down the line, from that point on, they could be connected to the load side of the last GFCI. =====gfci rec bath 1 || ||============gfci rec bath1 || ||=============gfci rec bath1 load side=======rec====rec || || || || gfci bath2 rec/load side=========rec===rec |

Doing that probably saved them hundreds of dollars. Today, it make little sense. |

=========================== You don't understand how a GFI works. GFIs do not look at the line VOLTAGES, they look at the load CURRENTS. You can connect anything you like anyway you like on the LINE side of a GFI and not effect its operation. In a way, the entire electric grid is in parallel on the line side. It is an imbalance in the LOAD side CURRENTS that trip a GFI. Mark |

Yes, the above is what I meant. You're right, the way I worded it, it was misleading. In the OP's case if he just put another GFCI in the second bathroom, it would be downstream from the first GFCI in the first bathroom. That is what I was addressing. Could you clarify that for me? So, if I understand it correctly, what you'd like to have is one GFCI in each bathroom. That GFCI in turn would protect the other downstream receptacles in that bathroom.

Right. I wanted to show the more general case. We don't know where it's connected. If it's connected to the last of 4 GFCI's in the first bath, then he'd need 4 GFCI receptacles in the first bathroom. In the example, he needs two. If it is, then those first 2 "gfci rec bath 1" are not needed. I say that just in case the OP missed that subtle point. Yes, if bath 2 ties in at GFCI one, then he only needs the existing GFCI. But with Murphy's law, it's probably tied in on the last receptacle. Actually I just read it again and it's 3 bathrooms. Depending on the sizes, usage, etc, he might want to consider pulling a new circuit to split the load. Two hair dryers at the same time and you're pushing it. |

Maybe this explains why, when my GFCI breaker failed, the price shown beneath it in the store for the new one was a lot, but when the cashier rang it up, it wasn't much at all. |

Not if it's wired the way I described and showed it wired above, which is the same way that DerbyDad is saying. The GFCI protected portions of the circuit are separate from one another. They are not daisychained, ie, with the second one being connected to the load side of the first. A fault on one will have no effect on the other. |

I think what folks are saying is that you should daisy chain from the line side of the first gfci to the second room where you put the gfci, and daisy chain from the line side of the second gfci to the third bathroom. That way, each gfci sees an uninterrupted power source back to the circuit breaker/fuse box. Each bathroom can then daisychain from the load side of its respective gfci to any other outlets and maybe a ceiling light in that same bathroom.
The only shortcoming of this method is that when the ceiling lights are also on the protected side of the gfci, if it does trip, you will lose all power to the room and it will be totally dark unless it is daytime and there is a window in the bathroom. At night you are SOL if that happens. |

Greg I agree that it would be a good idea to have more than one circuit. I suggested that he consider the option of running a new circuit. But what he has, with non-GFCI receptacles is apparently working. At least he's not complaining about it. Changing them to be on separate GFCIs doesn't make any difference with regard to the possibility of the load of 3 hair dryers. Nor is there a safety hazard, as long as the circuit has the proper size breaker. |

Maybe he needs to find the root cause of the tripping before he start rewiring his house. |
