Electrical Question from Mike about Hot Tub Wiring
Background: Mike, a Electrician from Pittsburgh, PA
Question: Homeowner wants me to install a 220V hot tub. She said the run is about 220 feet, and I did not have to drill holes as there is a duct. I have been working as an electrician for the past three years, and I know you can’t do a run inside a duct, you can tun through a cold air return, but as far as i know, you cannot run the length of a duct. Also, for the 220, should I use 6/3 with an insulated ground?
Additional Comments: LOVE YOUR WEBSITE!!!

Thanks for your electrical question Mike.
See:Â NEC 300.22 Wiring in Ducts, Plenums, and Other Air-Handling Spaces.
The wire size must be increased due to the length of the run.
The wire MUST be Copper.

The Safest Way to Test Electrical Devices and Identify Electric Wires!
The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use. |

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!
The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..
The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use. |
