Answer This Question

A:  Hello Butch, Your question is not clear regarding your application. The PK4MB2HA is a retaining kit for a back fed main breaker for convertible load centers 150A-225A series S01 and S02. The QO1HPLCP is a circuit breaker padlock attachment for a QO 2 or 3 pole circuit breaker. You did not mention the load center this is being used with. Please call 888-778-2733 option 2 to explain your application. Regards, Customer Care Center

    Answer This Question

    A:  JP, Handle can be locked in OFF (O) or ON (I) position. If locked ON (I), attachment will not prevent circuit breaker from opening if tripped by circuit conditions. 1. Move handle to desired position. 2. From side of handle, slide center part to handle center. 3. Lower both end parts on either side of handle and install padlock. I hope this helps.
