After the switchgear equipment is first installed, all necessary interlock keys should be inserted into the
appropriate locks and all spare keys should be placed in the hands of a responsible person. Refer to the key
interlock schematic included in the summary furnished with the equipment. You can then determine the
sequence of operation and correct number of operating keys required. This precaution is necessary since
improper use of spare keys defeats the interlocking scheme. There are many other interlocking lockout and
tag-out combinations. Some use two or more keys.
