Ask 'Dr. Spa' Q & A Message Board

: John, again I appreciate your help. Let me say that I only want a SAFE installation. I am the spa owner and I am way, way out in the West Indies. I am not concerned with code as there is none out here. I understand the UL and ect, but really would like to know if two #12 AWG installed as one wire will suffice for one #6 AWG? Thanks much.Galen

I have seen parallel conductors on heater circuits a number of times,
: but the tub was certified by UL in this configuration. Personally, I
: am not a fan of parallel circuits, but they can safely serve certain
: purposes.

: This particular case is a different matter. NEC Article 110.3(B)
: specifically requires electrical equipment to be installed according
: to the manufacturers instructions. The UL or ETL certification is
: predicated on the equipment being installed in the recommended
: manner. The minimum wire size and/or type specified by the
: manufacturer must be adhered to. This is mandatory (well, at least if
: we want a safe, code compliant installation).
