Default Receptacle above baseboard heat

Are there any restrictions on putting
receptacles above baseboard heat? Can I put a receptacle above a
baseboard heater knowing full well that someone will plug something into
the receptacle and allow the cord to drape over the baseboard heat? If
yes, does it depend on the type of heat - radiant heat vs electric
baseboard for example?
Is there a different ambient temp in the wall for derating of the wire?

To add to what Voltz has written, I will say that I have never seen an electric baseboard heater that would allow a receptacle to be installed above it.

Here is the accessory to accommodate code. They mount at the ends of the heaters. I have done a few this way but not for 20 years or more.

I also did some like this many years ago, but I never liked it. My reason is;

Most electric baseboard heaters operate on 240/208 volt. Therefore you had to bring a 120 volt line to the receptacle, and by code the unit would have to be identified as having more than one power.

Not sure what code that is but anyone should be able to see that there would be 2 power sources. I never labeled it. Maybe back then it wasn't necessary.

The NEC does not address this. It would be in the manufacturers instructions. I seem to remember something like 4' or so.

Yes, the purpose is to keep cords from draping ontop of the heater. I don't believe there is an issue with a floor recep. in front of the unit.

Here are some instructions from a Cadet heater. Seems like no recep. is allowed above the heater at any height.

Quote:
1. Read all instructions before using this heater.
2. Read all information labels. Verify that the electrical supply
wires are the same voltage as the heater.
3. All electrical work and materials must comply with the
National Electric Code (NEC), the Occupational Safety and
Health Act (OSHA), and all state and local codes.
4. The heater must be grounded to the grounding pigtail (copper
wire) provided.
5. If you need to install a new circuit or need additional wiring
information, consult a qualified electrician.
6. Protect electrical supply from kinks, sharp objects, oil, grease,
hot surfaces or chemicals.
7. Do not place heater against paperboard or low-density
cellulose fiberboard surfaces.
8. Do not place heater below an electrical convenience receptacle.


Quote:
Placement
For best results, install the baseboard heater under a window, along
an outside wall, or as close as possible to an outside door. Follow
these instructions for selecting an ideal area of installation:
the heater may need to be caulked to prevent dust from being drawn into the room.
Heater should be set flush against surface of the wall.
Remove any obstructions between the back of the unit and the surface of the wall.
Baseboard heater may sit directly on any floor surface, including carpet.
Do not allow carpet to block lower air intake located 1 inch from the bottom of the heater.
Maintain at least 12 inches minimum clearance from objects hanging above (i.e. drapes).

Dennis; Our code is the C.E.C. There are amendments for specific provinces. You have amendments for specific states I think.

heh someone doesn't want to come to this new house then. The whole house is wired with electric baseboard heating and it's under every window basically and under every outlet in the house. It'd be impossible to follow code to meet the minimum distance of outlets if they didn't put it over the baseboard heating.

Floor recep. would make it compliant and recep. in the end of heaters. Why would that not work?

Good question I suppose that would of worked however I didn't wire the place a Master Electrician built the house back in 1995 so perhaps the rule wasn't in effect back then.

Yes it was, the inspector didn't catch it would be my guess. It is not an NEC issue but a manufacturers spec.

Thanks for all the input. Would I be able to install a panel board above the baseboard since there would be no cords hanging.

That depends-- technically it would violate 110.26

Quote:
(3) Height of Working Space. The work space shall be clear and extend from the grade, floor, or platform to the height required by 110.26(E). Within the height requirements of this section, other equipment that is associated with the electrical installation and is located above or below the electrical equipment shall be permitted to extend not more than 150 mm (6 in.) beyond the front of the electrical equipment.

Not 'imposable' at all and the job should fail.

Either use the receptacles that install in the baseboard or never run more than 12' continuous feet of baseboard heat.

In new construction, I have had to install 2 small heaters with a space between, to comply with the receptacle spacing rules. A little more work and expense. But an option.
