I have a question about using an existing 240v plug in my garage to attach a heater to it. The wiring was done initially if I ever wanted to use a welder. It's never been used for a welder but I like having the option.. The plug is on 2 30 amp breakers. I am looking at potentially purchasing the heater I have attached or something similar. The wiring itself is not difficult to me but my question is, is my plug completely useless now and I have to get rid of it or can I tap into the line for the heater and still have access to my plug. I am guessing if it's the second, I will not be able to use the outlet anymore. I hope this makes sense.
