Loose-fitting plugs are a sure sign of worn-out receptacles (outlets). Replacing old outlets and switches isn't difficult, it just requires some common sense and following the rules.
Instead of running extension cords and splitters, I just hot-wired this workbench with a couple of outlets in metal junction boxes, and used part of an extension cord to supply power to the outlets. Power problems solved.
When the end goes bad, don't throw away the whole thing, just replace the bad part.
It's recommended to replace smoke detectors every 10 years.
And sometimes smoke detectors just go bad.
Replacing an AC interconnected smoke alarm is not difficult and requires just a few tools.
This ordinary light fixture with a glass globe can be installed in a few minutes with common household tools.
Remodeling work can get a little crazy, and its easy to accidentally cut a wire. Repairing a cut wire requires a junction box and enough slack to make the connections.
My backyard was too dark, so I ran a wire from the back door area through the attic to the soffit and mounted an outdoor junction box to a rafter. Then I connected a twin bulb-holder and screwed in a couple of compact fluorescent floodlight bulbs. Darkness banished.
When you open the box, a ceiling fan can seem like a daunting installation project. When the job is broken down, it's not so difficult.
A chandelier is installed like any other light fixture. The medallion adds thickness, so a longer threaded tube and longer screws are required.
This type of close-to-ceiling light fixture is very popular, but can be tricky to install.
There was no light over the sink in this old house, so we ran some wire through the attic and installed a short section of track.
We often use laptop computers at the kitchen table, and running extension cords across the floor created a tripping hazard. So we cut a hole in the kitchen floor and installed a floor outlet.
During remodeling I ran some 14-gauge 3-conductor wire throughout the house to supply power to a half-dozen interconnected AC smoke detectors.
If I want to replace the main breaker panel someday, the inspector will require this.
When adding new wiring behind existing walls, special "old work" J-boxes are used. These simply clamp to the wallboard, but the hole must be cut carefully.
A round hole is cut in the ceiling so the J-box can clamp to the drywall.
This house had new thincoat plaster over special wallboard... all over wood lath. The wall was very thick so installing "old work" J-boxes was tricky.
While installing cabinets, we realized that this outlet was in the wrong spot and needed to be moved over a few inches.
When electrical wiring enters any metal junction box, there must be a way to secure the cable. The most common method is a cable clamp.
To provide power to a new light fixture, we removed an outlet and fished new cable into the junction box. Once the light fixture and switch were done, we connected the new wires to the existing wires behind the outlet.
Wiring a dimmer switch is no more complex than an ordinary switch, although many dimmers have short pigtail wires instead of screw connectors.
Many home appliances don't come with a power cord. Connecting a power cord to a stove is straightforward.
Instead of using a bulky surface-mounted range outlet, we installed a large metal junction box during remodeling. After drywall and painting, we installed a big 50 Amp stove outlet. This compact connection allowed the stove to be pushed tight against the wall.
Since a recirculating-type range hood has no outside vent, there is no ductwork to connect, just the electrical supply.
We installed this super-quiet Panasonic bathroom exhaust fan after the room had been drywalled, because we had good access to the attic above. Installation involved fastening the metal box to the ceiling joists, connecting the ductwork, and wiring the power supply.
Installing a new electrical circuit means running a cable into the breaker panel, connecting the wires to the right places, and installing a new circuit breaker. Not a difficult job and plenty safe... if you turn off the power to the panel.
When a new electrical cable needs to enter a breaker panel, a metal knockout must be punched out. To protect the insulation and secure the cable, a cable clamp is typically used.
When a bunch of new circuits are needed in one part of the house (such as the 2nd floor), it's easier to run one fat cable to a subsidiary panel and then branch out. Read the overview article or parts 1, 2, & 3 below
The back side of the wall had been gutted for a room remodel project, so cutting the wood lath and plaster was easy... with the right tools.
A big #6-3G cable is brought into the main panel and connected to a 50 Amp tw0-pole circuit breaker.
The new sub-panel is prepped and fastened to the wall, and the 6-3G subfeed cable is brought into the panel and connected.
