Sample interview questions: How do you ensure proper insulation and protection of electrical wiring in residential buildings?
Sample answer:
Proper Insulation and Protection of Electrical Wiring in Residential Buildings
-
Use AWG-rated wire: Choose wire with the appropriate American Wire Gauge (AWG) rating for the amperage and voltage of the circuit. Thicker wire (lower AWG number) provides better insulation and protection against heat and damage.
-
Color-code wires: Standard electrical color codes designate specific functions for different wires. This helps identify wires during installation and maintenance, reducing the risk of misconnections and electrical hazards.
-
Use proper wire connectors: Crimp-on or screw-type wire connectors provide secure, insulated connections between wires of the same gauge. Twisting wires together without connectors can lead to poor connections and electrical faults.
-
Install wire nuts: Wire nuts are insulated connectors used to terminate multiple wires at junction boxes or light fixtures. They provide a secure, weatherproof connection that prevents accidental contact and shock hazards.
-
Use conduit or raceways: Conduit or… Read full answer
