bathroom electrical layout questions


wanted to get feeback on my crude wiring diagram i put together for my small bathroom remodel. does it appear to be sound or am i way off base??

details:

* 20A dedicated circuit
* 12/2 wiring
* outlet's will be GFCI
* double gang box will contain:
* timer unit for exhaust fan
* double switch for heat lamp and lights
* Ground wiring is not shown but each fixture/outlet/switch will be connected to ground wire
* by calculations, the 34cu box is fine for the number of conductors/size of wiring. per box specs could handle 15/12g wires.
* the scanner cut off the bottom part of the picture, the 2 lights on the right are fed from the same switch, neutral's connected together.

F = Exhaust Fan
L = Light
HL = Heat Lamp
T = Timer switch
S = Switch
H = Hot
N = Neutral
Wire Nuts are in the box connecting the pigtails

Thank you for your input.

bathroom electrical layout questions


What is the wattage of the heat lamp? Of the lighting and fans? since you will have fixed and cord connected loads the fixed loads need to be less than 10 amps.

Unless called for the lighting etc will not require GFI protection.

Hi Jim - Thanks for quick response. The HL is a 250W and it's one of those broan 162 fan/HL combo's. Per the specs it draws 2.5 amps but now I just noticed this stamped on the label: "15 amp branch circuit only". Does this mean that I cannot use a 20amp circuit? The other lights will be roughly 250 watts total.

Even though it is only 250 watts does it call for a dedicated circuit?

bathroom electrical layout questions


the paperwork that came with the fan does not state it needs to be a dedicated circuit. on the inside of the unit there is a sticker that reads "only 15amp branch circuit", though nothing about dedicated. i looked online and there are a couple sites that say 20amp dedicated is required.. the broan site itself does not mention this however though it looks like the fan/lamp combo are actually 300 watts, not 250 as i stated earlier.

here is what is listed on the broan site:

MODEL VOLTS AMPS WATTS* SONES CFM DUCT
162 120 2.5 300** 3.5 70 4" Round
* Total Connected Load
** BR40-size Infrared Bulbs. Use

Since the receptacles are GFCI you may need to use pigtails. They don't have the double screws for in and out. Some do have the connections that use the flat plate to clamp the wires and allow two wires under each screw. Use only the LINE connection if you are using two separate GFCI devices.

Where are you located?
I would guess this is considered a light, and lights in Canada can only be on a 15 amp circuit.

If you have enough room in your breaker box, or can install a tandem breaker, figure minimum two circuits, three if needed. Two for lighting, one for receptacles. I have my lighting tied into my bedroom and hallway lighting. If ever needing to go with 20 amp for that circuit, I can pull that one out of the junction box in my basement and move to a 20 amp breaker, since I used #12 for both lighting and receptacles in my bath remodel.

Do yourself a favor and only run #12 for all circuits, and call it a day.

my panel is already overcrowded, i had to move some stuff around to get this one dedicated 20amp ckt. i do have another one i could pull that feeds and outside area that rarely get's used and put in a tandem.

don't have any #14 laying around and don't plan to buy any, agreed #12 all the way..

thanks for the advice everyone so far..
