Hi,
I have installed a new spa pack and pump into our hot tub (inherited with our house a few years ago). I need to rewire a small length between the kill switch inside the enclosure to the spa pack control unit, asn the old length of wire is a bit too short. The old wire is AWG 10/3 CU NMWU 300V FT1, which is also what runs from the breaker (30 amp GFCI, 240 volt). The electrical guy at the big box store sold me NMD90 XLPE 10/3 300V FT1 instead, saying that it was a suitable substitute for the NMWU. Is he right?? The spa is outside, and I thought that NMD90 was only for indoor protected dry areas? Granted it is inside the enclosure, but I wouldn't exactly call that a dry location.
Any help would be appreciated!
PS - whoops, my thread title was wrong - I meant NMD90.
