Unsafe wiring. Wiring deficiencies. Make repairs to electrical wiring as required, don't delay!!.

Common wiring deficiencies which are found in many homes.
Exposed wire splices. All wire splices and connections have to be made inside junction boxes and not in 'mid-air' to prevent damage, injury and fires.
Open junction boxes. Somebody worked on the wiring and 'forgot' to install the cover plate. Open junction boxes are a safety hazard and require a cover plate.
Exposed wiring (mainly in garages and workshops) should be protected from physical damage. This is especially important in the garage where wiring could be used for hanging tools.
Installing a few sheets of plywood will provide adequate protection and at the same time provide solid backing for tool storage and shelving.
Loose wiring should be properly secured to the framing members with wire staples. When using staples remember:
- The wire must lay flat when stapled.
- Do not overdrive staples. Pinched wires could be dangerous.
Receptacles with 'temporary' plugged in extension cords. Automatic garage door openers and freezers are often permanently wired by using an extension cord.

Most extension cords are only 16 gauge and are not heavy enough for permanent wiring. Install new receptacles where needed.
