ELECTRICAL ​TROUBLESHOOTING​​


  • Loose electrical connections

    There are two myths about loose electrical connections. One of the most widespread ideas is that infrared inspections are not necessary when all the connections are tightened regularly as part of a preventive maintenance program. Similarly, it is assumed that the thermal anomalies at electrical connections highlighted by an infrared camera are loose connections that can be corrected by tightening the fasteners. Both are false. 

    Looking into the repair records it was discovered that connections which were disassembled, cleaned, and reassembled had a 92 percent success rate. The ones which were just tightened had approximately a 20 percent success rate. It was concluded that the surface of the faulty connection had time to become dirty and oxidize.

     The reasons are usually two-fold: the chosen method of repair was incorrect for the type of problem, or the problem was not identified or diagnosed properly and maintenance was performed on the wrong component. To have a good connection, two elements must be taken into account--clean contact surfaces and proper exertion of force and pressure.

  • ​​Electrical code violation removal​​​

The National Electrical Code is not just an encyclopedic list of suggestions for wiring and other electric components. It's the law. Most municipalities require permits for home improvement projects, including inspections by licensed electrical inspectors whenever applicable. If they find code violations, expect them to keep visiting you until are in compliance - or face potentially hefty fines.

Before starting any project that might involve electric wiring, check local codes and regulations. In some areas, only a licensed electrician is allowed to do any electric work.

Here are a few electric safety violations that could cost you money. These are general national guidelines, but some municipalities may have additional requirements:

Standard receptacles in bathrooms and kitchens: Codes require properly installed outlets with GFCI (ground-fault circuit interrupter) protection for all bathroom outlets and most kitchen locations. These devices break the circuit if there is a difference in flow between the line and ground current, and are crucial near water for avoiding electrocution.

Inappropriate outdoor receptacles: Likewise, outdoor outlets must have GFCI protection as well as waterproof boxes and covers, and they must be at least one foot off the ground.

+ Ungrounded three-prong outlets: Many older homes have ungrounded switches and outlets, but most of our new appliances have grounded three-prong plugs. The easy (and typically illegal) solution in a "grandfathered" ungrounded house is to replace an old ungrounded two-prong outlet with a new ungrounded three-prong outlet. However, this is a code violation and a good way to destroy expensive gadgets. It is also a code violation to put metal cover plates on ungrounded outlets. The plate could be electrified.

+ Wrong-sized wires: If you aren't sure what gauge of wire to use on a given circuit, you probably should leave the job to a professional. Using the wrong sized wire can be dangerous.

Insulation too close to recessed lights: Recessed lights are very popular, and most homeowners want to insulate and weatherize their homes. It's a dangerous combination. Either replace recessed fixtures with more expensive models that are Insulation-Contact (IC) rated or make sure to leave the required three inches of space between lights and insulation.

These are just a few of the many electric code violations that could cost you money - and your house - in the event of a fire. Consult with local officials and professional experts before starting electrical projects.
