Electrical Wiring

Bathroom project electrical

16 years ago

I'll try to keep this short n concise with as much detail as i can...pardon my lack of knowledge in correct terms. Ontario, Canada, residential bathroom upgrade. Components and layout. 1 line run direct from panel to whirlpool tub. 2nd line run from panel direct to gfci outlet 1 run parrallel to gfci2 (this gives me constant unswitched power at vanity? from gfci1 to switch1 in turn to light1 above vanity. gfci2 to switch2 which will switch exhaust fan and main light. Do I need junction boxes anywhere? Can I safely run it exactly as stated with all components daisy chained if you will...no junction boxes? The present service is 100 amps being upgraded in roughly a month or so with a breaker style 200 amp service current is round fuse. Should I run and dead end an additional main line to seperate the two circuits after the upgrade or is my layout sufficient? The wiring has been changed from the old cloth covered 14/2 to new 14/2.

"2nd line run from panel direct to gfci outlet 1 run parrallel to gfci2 (this gives me constant unswitched power at vanity? "

Is this a run-on sentence? I don't understand what you're implying here. Break it down into short sentences please.
A "run" of wire from the panel is referred to as a circuit. You can have up to 12 devices ( a device is classified as anything that consumes electrical power) on 1 circuit in Canada.

When I say run then yes I am referring to a circuit, but I am speaking in the physical sense not in theory. A run being the physical line from panel to gfci1 for example. When I say main line I am referring to a single "run".

Step1) A physical wire to the whirlpool tub direct from service panel in basement.

Step2) A second physical wire from panel going to GFCi1.

Which in turn will connect to GFCi2 in parallel.

Step3) I will then run a physical wire from GFCi1 to Switch1 which will turn on the vanity light.

Question: GFCi 1 and 2 will have constant (unswitched)power as they will be before the switch running the vanity light, correct?

Step4) From GFCi2 I will run a physical wire to switch2 which will run a main bathroom light and fan which will just be hooked in series.

So what I am asking is if my physical layout requires any junction boxes or if I can wire it exactly as stated. I hope this clarifies my first post. Thanks for your response and time. Cheers!!

? about Electrical and Drywall for bathroom light
Q

Personally I'd do the drywall work myself (it's easy with patience) but you need to wait to see what you will have to fix. It could be that the other wiring is burried somewhere in the wall and can be recovered, but it also could be that they did an improper junction in the wall or they nixed the whole mess and did a new run so you'll end up with a junction box (which is a cap that can be painted like the ceiling). Drywall isn't rocket science...but I do recommend practice first with the texture. If it's orangepeal that's easy, but if it's knockdown you have to get the knack to get it right (which you can do with a practice bottle of the spray). If you knck it down too soon it just mushes badly, and if you knock it down too slowly it won't knock down but will instead crumble off. I make it sound harder than it is though...really, follow the directions and DIY it...it's really easy work for usch a small space.

Is electric in-floor heat enough to warm bathroom above garage?

Creative tile, can nu heat always work as a heat source was I miss lead to buy a radiator. I have nu heat and was told it was not sufficient for the volume of my space...I trust creative tile on this more than my plumber for those reading this looking for advice. He has helped solve problems I have had with my tile, I defer to his opinion on anything tile and floor related, my GC, who I respect and will use again, appreciated and listened to creative tiles advice when I had some issues. Creative's expertise is superb in my mind!

Small bathroom remodel & electrical - 25-27k, is this too much?
Q

Hi! Some years ago; I remodel an entire apartment in Richmond area in SF! There are lots of bad contractors in SF. I would be careful and get references that are recent jobs done, get their licenses and bonding insurance. Call or go online to check that their license and insurance is still valid. Finally, check with the Better Business Bureau inquiries on your contractor(s). The best lead to get a great contractor is by asking around your neighborhood and/or friends and acquaintances that had work done on their bathrooms. The price of $25K seems high to me but you will not really know unless you get four or five competing bids to see how they compare to one another. Choice the one in the middle is the way I go about it if I do not know anything about them and just guess. Never do that - guess! Base it on facts - like jobs they done recently - from acquaintance and friends. References from strangers are not that good since it could be a relative or a friend of the contractor!

Electric code bathroom trough sink
Q
Comments (3)
The sink is a trough sink with two faucets. So my question is if it counts as one sink since it has one basin, or two sinks because it has two faucets.

What size circuit are running the GFCI. If you are using a 15 amp circuit for the GFCI then you have no problems. If you intend to run a 20 amp circuit then you must run another cirucit or tap power from another circuit which is 15 amp. You are not permitted to put lighting on a 20 amp circuit.

I missed the part about using 14/2. I guess that means 15 amp circuits. You will be fine.

"Step2) A second physical wire from panel going to GFCi1. Which in turn will connect to GFCi2 in parallel."

You don't need GFCI2. You connect a regular duplex receptacle to the "LOAD" side of GFCI1 and then the second recept will be ground fault protected. This common setup saves you money.
"Step3) I will then run a physical wire from GFCi1 to Switch1 which will turn on the vanity light."

Connect the wire to Switch1 before the line side of GFCI1. There is no reason to GFCI a lighting circuit. That way if you do have a ground fault trip in the bathroom, at least you'll have lights to see what you're doing. Your device box for GFCI1 also serves as your junction box for the connection of the wire to switch1.

"Step4) From GFCi2 I will run a physical wire to switch2 which will run a main bathroom light and fan which will just be hooked in series."

I wouldn't do that either. I'd run your Switch2 power from before GFCI1 or from the actual device box at Switch1. Again, you don't want/need GFCI protection for lights and fan.

Because it is the code in Ontario.

Ok sorry for the confusion again my terminology may not be correct. When I say GFCi1 and 2, I am speaking of GFCi power outlets for use around the vanity .
