Hot Tub Electrical CircuitĀ  Panel Wiring
[ad#block]Electrical Question: I have a hot tub sub panel that has the ground and neutrals on a shared bar. I’m selling the house and the homeĀ  inspector said to separate the ground and neutral but I only have one bar can I just simply add another? Is this common?

This electrical question came from: Shawn, a Homeowner from Anchorage , Alaska.

Electrical Tips to Help You Wire it Right

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.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect 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.

    Hi Debbie,
    Typically a #8 solid copper wire is bonded to a terminal lug on the pump motor, or to a built in terminal of the casting of the motor. The motor should run even if it is not grounded, however by code, and for your protection, the ground wire must be attached as described.

    I have a Softub brand hot tub and the power kept kicking off and on and when I took the cover off the pump/motor unit, I found the ground strap was not connected at one end. I have a photo but I guess I cannot send it here. I cannot see where it is supposed to connect and I am hoping that is the problem, not grounded, motor will not run, correct? Any idea where this end of ground strap gets attached? Thank you. Debbie

    Hello,

    I have a pool that was installed 3 years ago. I am now having an above ground hot tub put in. My electrician says that he will use the same ground rod used by the pool equipment for my hot tub ground. Is this okay to do? Or should a separate ground rod be used for the hot tub?

    Also the manual says that the reinforcing rod or mesh in the concrete spa pad should be attached to a bond wire. My electrician says he knows what to do with this. Is this where you connect a #8 wire to the steel in the concrete to the hot tub?

    Thanks,

    John (homeowner in California)
