A variety of tools and equipment are required for inspecting electrical connections and wiring in HVAC systems, including multimeters, circuit testers, wire strippers, pliers, and screwdrivers. Additionally, personal protective equipment (PPE), such as gloves and safety glasses, should be worn to prevent electrical shock and other hazards. In some cases, specialized equipment, such as thermal imaging cameras, may be necessary to detect issues like overheating or electrical resistance.
