RooKie Posted March 20, 2009 Report Share Posted March 20, 2009 For a hydromessage bathtub can you use a stranded wire for your bonding in the 2005 code? I have the 2008 code with me but need to know what the 05 code said. Anyone? Here is the part of the 08 reference... 680.74 Bonding. All metal piping systems and all grounded metal parts in contact with the circulating water shall be bonded together using a solid copper bonding jumper, what's the 05 code say?

My earlier post was incorrect. I broke my own rule and didn't read the entire paragraph carefully. The '05 edition says: 680.74 Bonding. All metal piping systems and all grounded metal parts in contact with the circulating water shall be bonded together using a copper bonding jumper, insulated, covered, or bare, not smaller than #8 AWG solid. This doesn't exactly say that the wire has to be solid, the wire just has to be no smaller than #8 AWG solid. I suppose that the new wording clarifies the intent that the wire should actually be solid. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...

Jim Katen Posted March 20, 2009 Report Share Posted March 20, 2009 What's the reason for the solid bonding wire? I don't know. Perhaps they're concerned with corrosion. A solid wire has less surface area to corrode. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
