I just recently noticed a 240v 3 prong dryer outlet in my friends garage where I brew. It was hiding behind some scrap 2x4s. I've been planning a small HERMS upgrade to my HLT but was planning on using only a 120v element. Now that I've found this outlet my plans are changing for the better! Question is, how do I determine how much juice is available at the outlet? I'm not very experienced with electrical, but I understand the basics (120 v. 240, proper gauge wire for the amps, how to wire an outlet, how to ground a circuit, etc). I know that I could just go look at the panel, and I'll try that, but I'd like to know which type of metering tool I can pick up at home depot will tell me what I need to know.
Any suggestions, along with tips on how to use properly and safely, would be greatly appreciated!
