Hi all!
Before getting into this post, just wanted to say a quick thanks to such a great community. With the ideas, recipes, and how-to's I've found on this forum I've gone from brewing my first extract batch this previous February to having a full-blown (albeit ghetto) electric AG setup in my basement.
Which brings me to my question. I'm using 5500W elements on a 30A circuit, obviously only 1 element powered at a time. I realized that the switches I've been using are only rated to 25A, and that's where the concern is.
A 5500W element pulls about 23A - is it safe to use 25A switches on this circuit? I ask because everything I've seen has indicated that you should never exceed 80% of a component's rating.
I've searched on the forums and I see that people have successfully used 25A switches and 25A SSR's on a 5500W system, but I'd like to hear someone's opinion that has good understanding of electrical standards/codes. An EE friend of mine seems to think it's a bad idea, but he works solely on power transmission and this seems more in the range of an electrician with more practical experience.
Thanks in advance; hopefully I can contribute something here soon!
