  • Patent number: 7681421
    Abstract: An electrical panel lockout that locks the electrical panel door closed and prevents the panel cover from being removed. Two telescoping hollow tubes extend between two panel screws. Two slots in the ends of the hollow tubes slide under the screw heads of each of the loosened panel screws. The outer hollow tube and inner hollow tube extend across the panel door keeping it locked closed. The shackle of a padlock is inserted into one of the openings of the inner hollow tube to keep the device locked in the extended position onto the panel screws. The screw heads are encapsulated by the device rendering them inaccessible and preventing the electrical panel cover from being removed. Hollow tube extension fittings can be employed to increase the length of the device for use on electrical panels of larger widths. A guide screw attached to the inner hollow tube rides in a slot in the outer hollow tube to keep both tubes from separating.

  • Patent number: 6580041
    Abstract: A circuit breaker safety clip and associated method are provided to identify and secure circuit breakers in an open position. The safety clip securely engages a circuit breaker in an electrical panel such that the circuit breaker must remain in an open position while the safety clip is attached thereto. The size and shape of the safety clip are selected such that the safety clip does not contact, and thus does not damage, other portions of the electrical panel. The safety clip design also provides ease of installation and removal. Additionally, the safety clip may include a warning tag that is durably attached and is appropriately sized to be noticeable without blocking the view of other circuit breakers. Still further, the wrap-around safety clip design of one embodiment protects at least part of the circuit breaker, typically the head of the circuit breaker, from direct impact.

    Abstract: An image forming apparatus having at least two of a plurality of functions including copying, facsimile and printer functions includes a main power switch that is provided on an outer surface of the apparatus and a cover to cover the main power switch. The cover is capable of opening and closing. Because the main power switch cannot be operated unless the cover is opened, when a user inadvertently tries to turn off the main power switch, for example, at the end of a day, the user must first touch the cover and is thereby reminded that the switch which the user is trying to turn off, is actually the main power switch for the apparatus. Thus, the main power switch is prevented from being inadvertently or unconsciously turned off.
