Electrical Energy-savings Question:
We want to buy a chest freezer, no bigger than 7.0 cubic feet. (Hopefully, Energy Star compliant, but that depends if we can afford it.)

We wanted to put the freezer in a storage area found between our garage and dining room. It doesn't have central air or heat going to it, but it doesn't ever get as hot or cold as the garage (probably due to insulation.)

There is one outlet in the storage area, but it is not on a dedicated circuit. In fact, the circuit it is on carries the garage door opener (1/2 h.p., 120V/5amp, 60hz), the dining room light (uses 2 60-75 watt light bulbs and is on a dimmer switch), and two other regular outlets which are occasionally used to plug in the cell phone charger.

I am not sure what wattage a freezer would use, but I am assuming about at most 800-900 (surge) watts when the compressor turns on. The circuit breaker is 120V/20 amps. Would this overload the circuit?

We looked into getting a dedicated circuit, but that would make the cost of obtaining a new freezer prohibitive for us.

Thank you for you help!

Hi Lori - Great Electrical Repair Question!
First of all I would very strongly advise you to try to get an Energy Star Compliant freezer, or at least pay very close attention to the Yellow Energy Guide

Some freezers may say that they will only consume $25 of power per year. On the other hand you may find yourself with a real energy pig like a friend of mine who was given a freezer that cost him over $300 per month to operate (wow what a deal?)

If you find yourself a low consuming freezer then it looks like the circuit you are describing will work, the 20 amp circuit has 2400 potential watts available.

It is common to find a freezer in a garage on a shared circuit, rarely do they require a dedicated circuit.

Lori - I really hope this helps.

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.
