How to Select the Right Generator for Your Home Electrical Requirements


Select Your Generator Carefully
Generator Question: I was wondering if a generator could be hooked up to a hot tub for emergency heating only.
The hot tub requires a 50 amp breaker and pulls about 4500 watts with everything running.
What size of portable generator would be required and any special wiring needed?

This electrical question came from: Joe, a Homeowner from Iowa city , IA

Thanks for your electrical question Joe.

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.

    I live in the northeast and as you can imagine, have plenty of snow storm and blizzards. I have a hot tub which requires 240V, 50amp. I have a generator that can handle 7000 running watts and 9000 start up watts. My electrical box has a switch, so that if I loose power, I hit the switch in my breaker box, connect the generator and off I go. We have lost power before for over a week, and I am afraid of my hot tub freezing. I do use it all winter so draining is not an option. If I were to alternate my house (furnace, minimal lights, etc…) and every few hours switch to only the hot tub. Would my generator handle it?

    • Dave Rongey says:

      Hi Sue,
      The generator would bog down to the electrical demand of the heater which is in the hot tub. You may want to consider having a freeze stat installed on the hot tub. A freeze stat is typically set up to turn on the pump at a low temperature before freezing which will then circulate the water to help prevent freezing. A local hot tub installer or technician should be able to set you up with this.
      I hope this helps,
      Dave
