Welcome to our forum.
Chas,My husband went to check at the supply house (two different ones) for the Sub panel Square D and GE they said they never heard of a split 20/30 only the 50 for spa's. As I posted in my original GFCI topic, the first HS dealer said $400 (not such a nice guy) The other dealer Caldera said $150 and of course we'd still like a better deal, if there is one to be had. If you can help with a GE or square D P/N or otherwise please advise. Thanks a bunch!I gotta get this thing plugged in!
I sell the sub panel at my cost, most dealers mark them up the same as other merchandise.I am usually selling the sub panel to facilitate a sale, or a move of a spa I formerly sold etc. The new tubs come with them.
