Name two of the four ergonomic/strain reduction strategies that were discussed for installing control wiring
What is
-Use stab-in switches and outlets. For residential work, use self-locking stab-ins. For larger jobs, use stab-ins with a side-screw fastener.
-Use tool-less connectors, such as low-voltage spring action screw-less terminals where only a small amount of force is needed to insert wire, and no twisting is required. -These connectors are easier and faster to use, thereby increasing productivity and reducing ergonomic risks.
-When stripping wires use proper size or spring-loaded strippers that are in good condition (sharp teeth). This reduces the amount of pulling force required.
-Limit the time workers perform similar, repetitive tasks that affect the same muscle groups. For example, rotate hand-intensive tasks with lifting tasks.
