Re: CQD answer published Wed, December 26, 2018 - Hot Tub Conductor Sizes
Friday’ answer revised hot tubs. As an electrical inspector for 24 years I rarely came across a hot tube that did not require full size conductors in accordance’s with 110- 3b. Typically the enforcement required full size conductors be installed from the tub disconnect to the tub, however BEWARE I started to see manufacturer recommendations that require all conductors to be full sized from the source. Always read the manual from the manufacturer and have it available for the AHJ.
Hey John thanks for your follow up comment. You make a good additional point. The NEC rules must be followed but any instructions included in the listing or labeling of equipment must also be followed as stated in 110.3(B).
