to remove broken light bulb Safe electric wiring |
 |
Light bulb might get
broken or break off when unscrewing from socket... To prevent stuck bulb: spray WD40 to aluminum part of new bulb before screwing into light fixture... don't breathe WD40 vapor, and be mindful WD40 vapor is extremely flammable. Tools needed: Very small flat-tip screwdriver and needle nose pliers Turn power off, wear safety goggles Remove as much glass as possible using needle nose pliers Use small screwdriver and pry aluminum part of bulb inward away from socket all the way around the perimeter. Grab onto the aluminum with needle pliers Roll the needle nose pliers in same direction as unscrewing light bulb. Aluminum part of bulb will start to wrap around the pliers until the bulb finally unscrews. |
Multimeter Test for breaks in wire/ Test for voltage Most appliance require 80% rated voltage to function correctly Buy Analog multimeter Multimeters at Amazon Klein multimeter Electric testers at Amazon Clampmeter for testing amp flow on line Resource: How to test and replace element How to test thermocouple Element tests for 120 volts How to test wire |
Safety
when testing wires:
Never touch wet or previously flooded appliance. Never stand on wet surface when working on electric. Never stand on bare soil, put down dry boards. Tape tester leads to wood sticks to keep hands away from power. Use non-contact voltage tester before touching wires. Never touch or lean into any made of metal. Remove metal objects from pockets. Do not use oxygen or fuel accelerants in same room as electrical repairs Resource: Basic house wiring |

 Non metallic flexible cables must carry ground wire, but do not have hazard of short circuit causing injury from shock. Armored steel cable can be used as a grounded connection, and will protect wires from damage. Metal can be energized from an insulation failure. All conduit ...metal, plastic ... flexible and rigid ... must be attached to structure, and attached to enclosures, boxes. Movement, damage and deterioration are major cause of electrical failure. Buy: Non-metallic flexible conduit Power whip Armored cable Southwire armored cable cutter Pull boxes |
 Electrical tools must be insulated. Always best to disconnect power, but insulation failure, lack of proper grounding, grounded neutral, lack of GFCI, out-of-code wiring, generator operating without transfer switch, and other problems still pose a risk to anyone working on electric power ... even when breaker is off.
