Professional Electrical Work for Hot Tubs & Spas

All of the steps are important for hot tub moving and hot tub installation or spa moving and spa installation involves integrating the main house panel with a 50 or 60 amp breaker. Whether 50A or 60A is required depends on the number of pumps and size of heater in the spa. For most exterior spas, we run a 4-wire number 6 or number 8 wire to the spa location.  The size of the wire to be used is determined by the maximum current draw of the hot tub, the length of the wire run and the NEC or local codes and use thermoplastic nylon (THHN) insulated copper wire, never aluminum.

A Duck Box is placed within 10 feet of the spa, but no closer than 5 feet, a GFCI or ground fault circuit interrupter and manual disconnect/shutoff will be installed depending on local code requirements. The Duck Box with GFCI provides a safety shutoff near the spa. In the case of GFCI tripping, it is easier to troubleshoot when installed near the spa as well. 

The GFCI installed in this exterior spa panel (Duck Box) that is used for hot tubs is of the 4 wire type.  It contains a ground and a neutral since many spas have 110v components built in to them that require a neutral wire. Not all spas operate on 4-wires, and many older spas only had 3 wire service. Never connect a 4-wire hot tub to 3-wire service.  Other spa brands such as Hot Springs may require 2 independent lines which would then require 2 separate GFCIs as per their own instructions.

This type of conduit needs to be buried at a minimum depth of 6 inches for metal and 18 inches for nonmetallic conduit. The combination of rigid PVC conduit combined with short length of flexible is used as code permits.
