What should always be used when working on live electrical circuits?

Using personal protective equipment (PPE) is essential when working on live electrical circuits to ensure the safety of the worker. PPE includes items such as insulated gloves, safety glasses, face shields, and arc-rated clothing, which provide a barrier against electrical shocks, burns, and other hazards that can occur when engaging with energized components.

The primary purpose of PPE is to minimize the risk of injury in environments where electrical hazards may be present. This approach aligns with safety regulations and best practices outlined by organizations like the Canadian Standards Association (CSA) and the Occupational Health and Safety Administration (OSHA).

While wooden tools can provide some level of insulation and multimeters are critical for measuring voltage, using them does not replace the need for comprehensive personal protective equipment. Rubber gloves alone are also not sufficient unless they meet specific standards and are used in conjunction with appropriate PPE for complete protection. Therefore, personal protective equipment encompasses a broad range of safety measures necessary for safely working with live electrical circuits.
