Avoid Overloaded Electrical Circuits and House Fires


electrical safety By
Summary: Electrician Explains that Replacing a 20 amp fuse with a larger size will cause an overloaded circuit causing the wiring to become hot which could lead to a house fire. In a case such as this additional circuits need to be installed.

How to Safely Replace Fuses and Circuit Breakers


Electrical Safety Question:
I have three window air conditioners and a refrigerator on same circuit. The 20 amp fuse keeps blowing. The Landlord says to use 30 or 40 amp fuse. Won't this cause wiring to get too hot and cause a house fire?
Thanks- Sally N.

Hi Sally - Great Electrical Repair Question!
Yes Sally, you are correct and much wiser than your landlord!
Replacing the 20 amp fuse with a larger size will cause an overloaded circuit causing the wiring to become hot which could lead to a house fire. In a case such as this additional circuits need to be installed

The required power for the air conditioners should be identified to determine the size of a new circuit. While you're at it make sure you have smoke detectors that work. With a landlord like that you may need them!

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.
