A modular enclosure comprises a first enclosure having a first enclosure cavity and a first door, and a second enclosure coupled to the first enclosure, the second enclosure having a second enclosure cavity and a second door. A power handle may be connected to the first enclosure, and can be operable to turn on power to the second enclosure in an ON position or turn off power to the second enclosure in an OFF position. The modular enclosure may further include a lockout assembly configured to prevent the second door from being opened while the power handle is in the ON position, and to prevent the first door from being opened until second door has been opened.

Motor control centers have units or buckets with an extendable/retractable power connection (stab) assembly and one or more operating lever interlocks that include a unit latch to latch to a cabinet and a power connection position interlock that blocks the handle of the units or buckets based on position of the power connection assembly, optionally also including a shutter cam that slides a shutter right and left.

Motor control centers have units or buckets with one or more sliding shutters that controllably block access to a stab isolation port based on position of the operator disconnect handle using attached cams that slide the shutter right and left. A front panel of the unit or bucket may also be configured to pivot out about a long axis associated with a bottom long side thereof.

A safety device is configured to be attached to components in an electrical substation to provide a physical and visual barrier between de-energized components and energized components in the electrical substation. The safety may include a safety barrier board formed from an electrically insulating material and configured to be attached to fastening devices that attach the safety barrier board to components in the substation. Each fastening device may be an inverted-J-hook configured to be attached to a surface of the safety barrier board or a coupling link attached to a variable length fastening component and an attachment hook.
