Do you know how to wire an AC wall outlet or ceiling light? Have you ever done either?

Wiring AC mains is hazardous and must follow local electrical code (e.g., NEC) and, where required, be done or inspected by a licensed electrician. The fundamentals: always de-energize the circuit at the breaker and verify it's dead (LOTO / non-contact tester) before working. A standard North American receptacle has three conductors—hot (black, brass screw), neutral (white, silver screw), and ground (green/bare, green screw)—connected to the matching terminals; outlets can be wired and grounding must be continuous. A ceiling light similarly connects hot and neutral to the fixture (through a switch on the hot leg) plus ground, in an approved electrical box. Use correct wire gauge for the breaker rating, secure connections, and proper boxes/covers. Given the shock and fire risk, this is work to do only with proper knowledge and code compliance.
