FAQs
1What type of circuit breaker is the BD-D15 compatible with?
The BD-D15 is designed for molded case circuit breakers (MCCB) with handle widths of 20mm or less. It is not recommended for miniature circuit breakers (MCB) with narrower handles or industrial air circuit breakers (ACB) with wider handles.
2Do I need any tools to install the BD-D15?
No. The BD-D15 features a built-in locking screw that can be tightened by hand. Simply place the device over the circuit breaker handle, turn the screw until snug, and apply your safety padlock. No wrenches, screwdrivers, or additional tools are required.
3What size padlock can I use with the BD-D15?
The BD-D15 is compatible with industrial safety padlocks and hasp locks with a shackle diameter of 7mm or less. BOZZYS BD-G series insulated safety padlocks are recommended for full LOTO kit compatibility.
4How does the anti-tamper screw design work?
Once the locking screw is tightened onto the circuit breaker handle, the screw head is positioned at the recessed base of the device. This design prevents unauthorized personnel from accessing or loosening the screw while the padlock is in place, maintaining the integrity of your lockout procedure.
5Is the BD-D15 compliant with OSHA LOTO standards?
Yes. The BD-D15 is designed to support OSHA 29 CFR 1910.147 lockout/tagout programs. It physically prevents the circuit breaker from being switched to the ON position, fulfilling the energy isolation device requirement under OSHA LOTO regulations.
6Can the BD-D15 be used in wet or chemically exposed environments?
Yes. The nylon body provides strong resistance to water, oils, and common industrial chemicals. The chrome-plated brass hardware adds corrosion resistance, making the BD-D15 suitable for use in manufacturing plants, chemical facilities, utilities, and outdoor electrical panels.
