Electrical Maintenance and Repair



Troubleshooting & Repairing
Your Home Electrical Components

Basic tips to provide you the electrical repair and maintenance knowledge you need to troubleshoot & repair your home electrical components in a timely manner, including building maintenance and electrical wiring service. These tips are aimed at minimizing any electrical downtime and lessening your repair time.

Worn electrical weather seal

When the weather seal to an exterior source of electricity has been damaged, such as an exterior outlet box, it may be time to call in a licensed electrician to deal with this potential hazard.

Overheated Circuts

An overheated circuit breaker in a house's electrical box can potentially cause a serious fire. A licensed electrician should be called without delay.

Rigged Circuts

Circuit breakers are designed and intended to service one complete circuit. Homeowners are discouraged from rigging breakers to service two circuits. If such a situation is found in a resale house, a licensed electrician should be called in to correct the problem.

Breaker Problems

Some circuit breakers, such as "CU-AL" breakers, are not safe when used with modern aluminum wires. A licensed electrician should be used.

Matching Wire Gauge

Sometimes wiring will be installed improperly sized for the breakers to which they are connected. Either the breakers need to be made smaller or the wires replaced with heavier gauge material. Unless you're an expert, call in a licensed electrician to make the fix.

GFIC water-wiring safety

Ground fault circuit interrupter outlets are very important around kitchen and bathroom sink areas, where there are many opportunities for electricity and water to make dangerous contact. If such an outlet fails to trip with tested, it probably needs to be repaired or replaced.

Electrical panel box safety

Firefighters should not have to search through closets for a home's electrical panel box in order to disconnect electricity in the event of a fire. The panel box should be easy to find in a garage or on the exterior of a structure.

Recessed Lighting

If the rear components of a recessed ceiling light are covered by attic insulation, heat will build up in the unit and cause it to shut down. If that happens, the light fixture may need to be replaced. Consult a licensed electrician.

Entrance wiring drip loop

If drip loops are not properly installed, rain water can seep in and cause costly electrical damage. In some areas, the local utility company will fix it for no charge.

Tree limbs and power lines

Tree limbs that have grown too close to power lines should be professionally trimmed before a heavy storm causes them to fall and damage or dislodge the lines.

Covering the junction box

Electrical junction boxes should always be properly covered to shield the wiring inside. If the cover on any junction box in a house is missing, it should be replaced with extreme care. * The home owner should place a proper cover on this junction box and any others that have missing covers. Extreme care must be exercised.

Attic electrical safety

Improper attic wiring, such as wires spliced together outside of an approved junction box, is unsafe and could lead to a house fire. A licensed electrician should be called in to correct the situation.

Bad electrical box weather seal

A broken weather seal on an exterior source of electricity can be dangerous. It should be repaired by a licensed electrician immediately.

Wire splices should be in a proper box

Sometimes there are safe short cuts. More often, however, short cuts are unsafe especially when dealing with electricity. Improperly spliced wires, such as this one in the crawl space under a home, should be corrected as soon as possible by a qualified electrician.

Electrical wire splicing should be in a proper box

Sometimes there are safe short cuts. More often, however, short cuts are unsafe especially when dealing with electricity. Improperly spliced wires, such as this one in the crawl space under a home, should be corrected as soon as possible by a qualified electrician.

No gaps in the breaker box

When the power goes out, most homeowners go to their electrical panel box and start groping around in the dark to check the breakers. If there is any kind of gap between a circuit breaker, this can be dangerous since fingers can inadvertently come in contact with live wires. A plastic spacer from any hardware or home improvement store can correct the problem.

Don't alter control power box

The power connection to an irrigation system's control box should not be altered beyond the manufacturer's recommendations. It can cause the unit to overheat.

Proper ground connection

Grounding wires to metal plumbing lines is an accepted technique, but the ground connector must be attached to the pipe directly. If there is any barrier between them, such as a layer of paint, it will render the connection useless.

Grounding a microwave

When inspected and tested, this microwave oven was found to lack proper grounding, a potentially hazardous situation. Any qualified electrician can fix the problem.

Two circuts, one breaker

Circuit breakers are designed and intended to service one complete circuit. Homeowners are discouraged from rigging breakers to service two circuits. If such a situation is found in a resale house, a licensed electrician should be called in to correct the problem.

Replacing a receptacle

When an electrical receptacle has been damaged, it should be replaced. Replacement receptacles are readily available at home-improvement stores although they should be installed by someone with knowledge and experience.

Protective weather guard

If the protective weather guard to an exterior electrical outlet has been lost, it should be replaced immediately to avoid any injury or potential damage to the household electrical system. A replacement guard is readily available at home-improvement stores.

Conduit care

Electrical conduit is designed to shield live wires. If any piece of conduit becomes unsecured, it should be repaired or replaced without delay.

Conduit safety

Electrical conduit is designed to shield live wires. If any piece of conduit becomes loose, it should be repaired or replaced without delay. Failure to correct the problem can result in unnecessary damage to the equipment and a possible safety risk

One Breaker, One Circut

Circuit breakers are designed and intended to service one complete circuit. Homeowners are discouraged from rigging breakers to service two circuits. If such a situation is found in a resale house, a licensed electrician should be called in to correct the problem.

Light fixtures

When a light fixture stops working, the first step is to change the bulb or bulbs. If that doesn't work, check the fixture. If the fixture works, then the problem might be with the switch or the circuit in which case a qualified electrician should be called in.

Too Tense

When electrical service support lines attached to the service mast on a house are too tense, as shown here, the mast will start leaning, creating a hazard. A qualified electrician should be called in as soon as possible.
