FAQs
1What type of circuit breakers is the BD-D16L designed for?
The BD-D16L is specifically engineered for a select range of older, legacy-style molded case circuit breakers (MCCBs) that feature an unusually long handle closing stroke. Standard compact lockout devices are not suitable for these breakers — the BD-D16L's larger body geometry provides the clamping depth and coverage required for secure lockout.
2Do I need any tools to install the BD-D16L?
No tools are required. The BD-D16L features a built-in locking screw that can be fully hand-tightened. Once the device is placed over the circuit breaker handle and the screw is tightened, simply apply your safety padlock to complete the lockout. The screw head automatically recesses into the base of the device to prevent unauthorized access.
3What size padlock is compatible with the BD-D16L?
The BD-D16L accepts industrial safety padlocks and hasp locks with a shackle diameter of 7mm or less. BOZZYS BD-G series insulated safety padlocks are fully compatible and recommended for a complete LOTO kit solution.
4How is the BD-D16L different from the BD-D15 medium circuit breaker lockout?
The BD-D16L (100mm × 66.5mm × 32mm) is significantly larger than the BD-D15 (57.3mm × 37mm × 40mm) and is designed for legacy MCCB models with longer closing strokes that the BD-D15 cannot accommodate. If your breaker is a standard modern MCCB, the BD-D15 is typically sufficient. For older, deeper-travel breakers, the BD-D16L provides the necessary fit.
5 Is the BD-D16L compliant with OSHA LOTO standards?
Yes. The BD-D16L is designed to support OSHA 29 CFR 1910.147 lockout/tagout requirements by physically preventing the circuit breaker from returning to the ON position during maintenance, inspection, or servicing activities. It meets the energy isolation device criteria under OSHA LOTO regulations.
6Can the BD-D16L be used in wet or chemically exposed environments?
Yes. The industrial nylon body provides strong resistance to water, oils, solvents, and most common industrial chemicals. The chrome-plated brass hardware adds corrosion protection, making the BD-D16L suitable for use in manufacturing plants, chemical processing facilities, outdoor electrical enclosures, and utility substations.
