Remember: Anytime you work with wiring, be sure to turn off the circuit at the main breaker panel. The damage to socket and wires remains even after the bulb has been removed.
What it means: A light fixture has a bulb with a higher wattage than the fixture is designed for. Solution: Stay within the wattage limit listed on all light fixtures made since 1985.
Application: Upgrading Older Home Electrical Wiring. Construction Safety: All personal safety measures must be taken when performing remodel projects where you may come into contact with hazardous materials and environmental contaminants such as fiberglass insulation, vermiculite and asbestos, molds or mildew, as well as dust.
Estimated Time: Depends on the extent of the project, the type of wall coverings and structural construction and available access to the project area.
The signs of strain may be obvious—a tangle of extension cords and power strips sprouting from a single outlet—or lurking unseen behind walls, ceilings, and cover plates.
Protecting the Box Fuse boxes, like this one, are less common these days than circuit breaker panels, but they work just fine — unless someone installs fuses with a higher amperage than the wires can safely handle.
Estimated Time: Depends on personal level experience, ability to work with tools, work with electrical wiring, and the available access to the project area.
After that, he recommends getting a quick follow-up inspection every five years.
Precaution: Any existing wiring in the immediate area that may interfere with the installation should be identified and turned OFF and Tagged.
Notice: Installing additional electrical wiring or upgrading existing electrical circuits and wiring should always be done according to local and national electrical codes with a permit and be inspected.
(Tandem breakers aren't the same as high-amp double-pole breakers, which take up two slots with one circuit.) A label on each panel specifies how many circuits the panel can accommodate. What it means: You have a type of wiring, used in the 1960s and '70s as a cheap substitute for copper, that is no longer considered safe. These nuts have a special grease that stops corrosion while maintaining conductivity.
Make sure any replacement switches and receptacles are labeled AL-compatible. The practice is allowed, even for new construction. At a minimum, loose wires can cause a receptacle or switch to stop working. Solution: Check for backstabbed connections by removing a switch or receptacle from its outlet box.
Some electricians will patch the holes; others leave the patching to you.
