Parts Desk Insights
Best Use Case: Ideal for critical or frequently accessed breaker circuits where accidental toggle movement could interrupt power or affect equipment operation. Install on a compatible A/B series single-pole breaker to add a physical barrier over the toggle.
Common Issues: If it doesn’t seat cleanly, verify you’re using a single-pole A or B series breaker and that the panel/breaker face provides the standard mounting screw holes used by the guard. Confirm the toggle area aligns with the guard opening before tightening the screws.
