Some common electrical wiring issues you’re likely to encounter at home can be easily addressed, but the level of danger they present to your household can vary. In all cases, when attempting any home wiring repairs yourself, make sure to first turn the circuit off from the main circuit breaker panel. When in doubt, be sure to contact your local electrician.
High wattage light bulbs in low-wattage sockets can melt wires and cause fires. Make sure to never use a higher-wattage light bulb than a light fixture is designed for. In older fixtures (pre-1985) without written wattage indicators, stick to bulbs of 60 watts or less.
2. Uncovered Junction Box
This is usually an easy fix since the plastic covers for junction boxes only cost a few cents at a hardware store.
3. Lights Flicker When it’s Windy
This can be dangerous. The weatherhead where cables enter the house from outside has some frayed wiring that’s causing shorts. Contact your local electrical services provider to have the weatherhead replaced.
4. Not Enough Outlets
As long as the extension cords you’re using to make up for it are sufficiently heavy-duty, the risk of fires is low, but if you want more outlets, you’ll need a certified electrician to install them.
5. No GFCIs
Ground fault circuit interrupters are essential wiring equipment in any modern kitchen or bathroom, and without them, the risk of electrocution is much higher. They are inexpensive and fairly simple to install by yourself.
6. Overwired Panel
This is not an urgent issue until you’re considering selling the house, but it can be remediated by adding sub panels with extra slots, or by installing a whole new larger panel with the help of an electrician.
7. Aluminium Wiring
This is unsafe to have because aluminium corrodes in the presence of copper. Every connection between the two metals in your wiring system needs to be retrofit with a dielectric wire nut prepared with an anti-corrosive grease specifically meant for aluminium wiring.
8. Backstabbed Wires
After removing switch receptacles to check for wires that have been pushed in without anchoring, release said wires and anchor them properly to the receptacle screw terminals.
9. Ungrounded Receptacles
These two-prong receptacles should be replaced with safer three-prong outlets as long as wiring permits, and rewiring is in order if it doesn’t.
10. Plug Falls Out of Loose Receptacle
The receptacle is old and should be replaced as soon as possible to avoid arcing.
If in doubt, contact your local electrician for more assistance
