Final answer:
Electrical and lighting systems must conform to electrical safety codes, building codes, and device ratings.
Step-by-step explanation:
Electrical and lighting systems must conform to specific standards to ensure safety and proper functioning. The standards that they must conform to include:
- Electrical Safety Codes: These codes define the safety requirements for electrical systems and devices, such as wiring installation, circuit breakers, and grounding.
- Building Codes: Building codes in many developed countries specify safety requirements for buildings, including electrical systems. These codes often require proper electrical wiring, smoke detectors, and other safety measures.
- Device Ratings: Electrical appliances, fuses, and circuit breakers are rated in amperes (amps) to ensure their proper operation and prevent hazards.
