I'm installing one of the heaters below in my garage. It's 240v 4800w and will be aproximatly 25' of wire from the panel to the heater. My plan is to use a 20 amp double pole breaker, #12 thwn in conduit to a junction box with a double pole switch then a short peice (maybe 18") of 12-3 mc between the box and the unit. Is that an acceptable method or should I be using a 30 amp and #10? I probably don't need the switch but I want to keep others from using the breaker as a disconnect.

Thanks in advance for any advice.

@John Hook it's a 6 year old thread. But to answer your question, no a simple wall receptacle on a 30 amp circuit does not fall into a category as a "disconnect". Generally a pull disconnect is advised.

I only mentioned it due to the resistive load weakening the plug/receptacle connection over time. A direct disconnect or switch as you mention would be more viable.
