Installing electrical baseboard fry? I would like to install electric baseboard roast in 3 bedrooms on...
I would like to install electric baseboard roast in 3 bedrooms on the key floor of my 1959 house. I am remodeling the basement and hold access to the floor joists along the center of the vault, so I can feed wires. I plan to run a 12-2 rope on a 20 amp 240 volt circuit. Couple questions.
1) Can I run the electric wiring to feed the baseboard heaters, installed lower than a window, through the floor right subsequent to the wall? I am not sure how I can drill a hole through the base of the wall and still know how to feed the chain.
2) how many watts can I run sour a single circuit as explained? I have 3 bedrooms: bdrm 1 (8.5'x12')X10watts/ft2 = 1020watts (1000 watt heater), bdrm 2 (9.0'x12')x10watts/ft2 =1080watts (1000 watt heater), bdrm 3 (13.5x15.5) x10watts/ft2=2093watts (2x1000 watt heaters). Using my intelligence the circuit is 20ampsx240v=4800wattsx0.8=3840safe...am I too close or can I get away beside 1 circuit running 4000 watts of heaters in three rooms?
Answers: Place the heaters against the walls where on earth you want to install them and trace lightly beside a pencil around the end where on earth the connections will be. There should be a knockout coming in the backbone, knock this out and trace the hole on the wall. Run a drywall screw thru the center to make sure in attendance is no stud here. This is your target. Drill a small hole in the floor right below your imperfection and stick a wire or something you can see from below. Go downstairs and drill at an angle so you're at most minuscule behind the space heater up top. Now you can gouge the wall upstairs just adequate to get the flex and connector in the wall satisfactory for the heater to lay flat.
The electric wiring is a little too close, especially if your not exactly 240v. I would any use 2 circuits or increase to a 30 amp (10 awg copper).
It is best to check with your local codes. In the Electrical Code Simplified (B.C. Canada) you can use 14-2 rope on a 20 amp breaker for a total of 3600 watts and 12-2 on a 30 amp breaker for a max. of 4800 watts. Some codes permit 2 flex conductor without the indeterminate. Try to keep your runs short and within a place where a staple cannot be driven into it where it is covered by sheeting or flooring. The grounds for such high wattage's is because baseboard heaters are fixed loads. Some codes may require a colored cable to identify it as a kiln wire. The breaker should own a tie bar.
Depending on local codes you can drill a hole surrounded by the wall and directly up from the basement. Or drill through the floor near a short piece of conduit for protection along the inside of the wall.
