Please help fight my ignorance.
My wife is looking for an electric space heater for a small room where she likes to read. The whole floor is on one zone, and we don’t want to heat the area just for this small space.
She is seeing a number of units advertised as 15A, 1500W. Now, I always thought that a space heater shouldn’t draw more than 75% of the circuit, for safety and in case someone should flip on a light or similar.
I haven’t purchased many space heaters, but I do seem to recall that the occasions when I have the largest 110V units I saw were about 1100 watts, which gels with the above.
My question is whether I was mistaken about what I thought was a rule (as opposed to guidance), or whether this is a case of legions offshore Amazon sellers peddling product that hasn’t been designed to proper standards.
