I'm installing a 240V 50Amp Jacuzzi at a residence. What is the minimum/maximum distances for the disconnect? Where can I find this in the NEC?

Many thanks,
Byron

Article 680.40 states: Electrical installations at spas and hot tubs shall comply with the provisions of Part I and Part IV of this article.

So, in short, the disco must be within sight and at least 5' away from the hot tubs inner wall, and not more than 10' away.

Within sight but at least 5 feet away.

680.40 General.
Electrical installations at spas and hot tubs shall comply with the provisions of Part I and Part IV of this article.

680.12 Maintenance Disconnecting Means.
One or more means to disconnect all ungrounded conductors shall be provided for all utilization equipment other than lighting. Each means shall be accessible and within sight from its equipment.

680.22 ...
(C) Switching Devices. Switching devices shall be located at least 1.5 m (5 ft) horizontally from the inside walls of a pool unless separated from the pool by a solid fence, wall, or other permanent barrier. Alternatively, a switch that is listed as being acceptable for use within 1.5 m (5 ft) shall be permitted.

Make sure to check with your local building Dept. They change the rules some places. We get a print out from the local bld. dept. when pulling permits for spas that are a little differant than code. Rod
