don't forget aluminum tape. u will need that to keep your heat tape in place in the rack.
also will each piece of heat tape have it's own plug? or will they all be wired together to run parallel?
if they are all wired together resulting in 1 plug, u can plug that directly into your Herpstat.
if they will 3 separate pieces resulting in 3 plugs, u might want to get a powerstrip and plug all of them into that. then plug the power strip into the Herpstat.
Yep... got that covered. I may not use all three shelves for a while, so I thought about putting each shelf on it's own switch, but have just decided I'll get a power strip. Thanks for thinking of that though.
