wiring electric heater


I have a 240V, 30 amp receptacle in garage. I want to ceiling mount a 240 electric heater ( draw of 21 amps) and plug it into the current recepticle. Can I have the wire from plug to heater secured to wall without code violation? If it is a violation, what must I do to connect heater to circuit and meet/pass code?

The cord from the heater must be less than 6'

O.K. then I plan to run a new line to a ceiling junction box and then run a wire to the heater. Must I use separate wires ( no cover/jacket) inside a metal flex-conduit for this short distance? For the 3 ft distance from box to heater, can I run the jacket/covered wire without a conduit?

no separate wires to be used. From the junction box to the heater use flex or AC or SO rubber cord.

Just make sure you are aware with conductor size you will need 6.0mm { 10 AWG } if you going to use the 6.0mmX3 { 10 -3 } SO or simuair cord you will have to remark the white conductor with tape or marker so you know you are on 240 volts.

And the other thing keep in your mind the cords count is diffrent than standard building cables { NM or UF,. etc }
The cords will count all conductors while the building conductors useally count the line et netural conductors but usealy not the EGC unless it marked.

Merci,Marc
