When I first read this post, like a lot on here I was in favor of it.
After more thought I changed my mind.
What if some one in a older house with knob and tube wiring
had a 240 volt 20 amp. Portable stack heater and had no receptacle for it.
And a friend offer to lone this unit to them until they could have
one installed.
Being an Electrician I know how much more 240 volts can be
Than 120 volts as far as being a fire hazard with a loose connection.
But most people don?t know this.
Now knob and tubing circuits may be OK for a 20 amp. Load at 120 volts and
I did say may be. But I think it would be a very dangerous fire
Hazard at 240 volts on a knob and tubing circuit with a loose connection.
If this unit was mass produce and sold by the thousands it more
and likely would be used this way.
I?m not a fanatic on stray electromagnetic fields like a lot in this field, but
if I where I would be dead set against this unit being legal.
