are the two plugs internally wired in parallel or series?
They are externally linked via a jumper you can snap off. Look on the sides, it will be between the two screws. Also, it's parallel.

All outlets and fixtures on a service branch are in parallel.
Think about what would happen if they were in series. Your reading lamp plugged into one outlet would get no power if you unplugged your phone charger from the other. Hell your phone charger wouldn't work unless you had your reading lamp turned on.

Cont. Afterthought...
A GFCI receptacle plugs are parallel, but they have a line and load side that you have to be aware of when writing it up. You'll know if it's GFCI because it's a fucking brick of a receptical that can be a pain in the ass to fit into the box.
Was trying to think of a way to determine which outlets in the same circuit are where in the series. I forgot how I wired it. Trying to find the first to put a gfci on it and save some money by not putting it on them all. Guess I'm gonna have to do it the hard way.
>>903963
I'd take the time to ring the wires out with a multimeter, that many gfci's can get expensive.
>>903964
Yea. I was hoping they might be wired in series (doubted it, though) so I could hook up a few time delayed devices on each branch and see which outlets light up first.
It would be a pain in the ass, but pull all recepticals out, turn power back on, and find the box that's hot. There's your box that needs the gfci.
Common sense needs to be applied using this method or someone could get hurt.
two plugs will always be in parallel, otherwise you would have to plug into both of them to get a complete circuit.
>>903967
Actually I'm an idiot... it would work...
>>903970
Never mind. Long way it is
>>903971
If you've got 2 circuits in that room. Turn off 1 breaker and mark the hot and dead boxes. That way you don't cross the circuits when you pull the recepticals.
>>903963
You're gonna burn your house down.
Also, you have Ground fault breakers in outlets in the US? Why the fuck not just put it in the fuse box so you don't have to secure each point individually?
>>904093
Gfci breaker=$35-$60
Gfci outlet=$10-$20
>>904108
you have lots of circuits with one single outlet on it?
you have to change them all to current leak detector outlets vs one off for the same cost?
>>904139
One gfci outlet will protect every outlet downstream from it, if wired correctly. That's why he's trying to figure out where the start of his run is.
>>904156
question, if I have multiple gfci outlets on one string, and one blows, will it cause the others to trip as well? IE will I have to press reset on all the gfci plugs on that string before they will work? or just the one that the faulty whatever was plugged into? I'd swear I've seen it both ways and want to know if I was mistaken or if it can be wired as such? thanks in advance.
>>904164
Not a professional, but I'm 99% sure gfcis can be wired either to protect the whole circuit, or singly. In that case, if you're really willing to pay that much per outlet, I'd wire them singly to avoid just what you're asking. Again, definitely NOT an electrician here, though I did wire my addition myself and passed the inspection no problem. Any electrician anons out there?
Multiple gfi on 1 circuit is redundant and offers no additional protection but a far greater cost. If you did for some reason do this, in a perfect system all gfi in the circuit will detect a fault and all will trip.

thx, not the op, but >>904164
mainly ask because the two bathrooms in my dads house, despite being on different floors, and on different sides of the house, share a breaker, and both have a gfci... found out the hard way if one trips, then both must be reset... have since run into it where it was not so, was just curious. honestly I think I could do some electrical work, but beyond replacing a dead light fixture, or crappy outlet or switch I'd rather pay to have it done... if I fuck it up and burn my house down it's just not worth it.... if some contractor does then my homeowners insurance ruins his life and makes mine hell while I rebuild.... at least in theory....
>>904171
Electrical apprentice here.
Having a GFCI at the head does protect all the boxes after. I've been told uou can have up to six outlets after and shouldn't have problems.
The other fun thing if that if you put a GFCI outlet on a GFCI breaker they will fight eachother and cause premature failure of either component.
>>904176
I had a gfci giving issues in a bathroom, lights on the circuit were doing this really fast flickering thing. I checked everything I could think of, no loose connections anywhere, no rats chewing on wires, changed bulbs... Finally the outlet tripped and once I'd set, tripped, and reset it a few times the flickering stopped. I'm going to guess that these outlets have contacts that can corrode, and the monthly check we're supposed to do takes care of that, in part.

This, I'm an apprentice and people who want a GFCI wired into a shallow box should be guillotined.
