Choose the right wire size for the application — using one too small can lead to overheating and potentially cause a fire.
Follow proper installation procedures, especially with the electric meter, electrical disconnects, electric panels and sub-panels. Use a conduit to protect the wire from damage and ensure the wire is grounded properly.
Be aware of potential hazards, like exposed wires or live circuits.
Take appropriate safety precautions, such as wearing protective gear and turning the power off before beginning work.
Label and identify the wire properly, both to ensure electrical code compliance and to make future maintenance and repairs safe and effective.
Check your appliance wiring and its electrical connection regularly. This includes small and large appliances, from radios and coffee pots to electric ranges, ovens and refrigerators. Make sure you’ve installed dryer cords, range cords, ovens and dishwashers properly. Check how these appliances are connected to THHN wires and other electrical wires.
Keep in mind there are good and bad electrical wiring connections. Note that a flooded home may pose dangers to your electrical wiring connections. Check whether you are making the proper knots with the electrical wires.
