Plug having common specifications are arranged on the side surfaces of each of the devices of different types included in the drive apparatus that controls an electric motor, and the plugs are positioned such that the side surfaces of the devices are in close contact with each other by connecting the plugs and the devices of different types are integrated.

Disclosed herein is an apparatus for providing and monitoring a temporary electrical supply, which comprises a portable electrical panel with an array of circuit breakers, an array of electrical plugs for supplying a temporary source of electricity, and an array of amp and voltage meters that detect information needed for each corresponding phase. The Temporary Electrical Panel is supplied by a 50-amp cord and has a 40-amp main breaker. Each electrical plug is rated at 20 amps, tamper resistant, and GFCI protected, with a dedicated 20-amp breaker. The electrical plugs may also be color coded to differentiate which phase they are on. Additionally, the Temporary Electrical Panel comprises a plastic backing board with handle cut outs or a handle, which allow the Temporary Electrical Panel to be carried.

A DIN clip apparatus with a housing in which components are disposed. The housing has a bottom edge which abuts the DIN rail when the apparatus is mounted thereon. A DIN clip is attached to the bottom edge of the housing. The DIN clip includes a DIN clip body that is disposed to a first side of a DIN rail. The DIN clip body has a first end which is closest to the DIN rail, and a second end which is farthest from the DIN rail. A DIN clip arm is pivotally attached to the first end of the DIN clip body. The DIN clip arm is configured to span the width of the DIN rail and to pivotally transition between locked and unlocked positions. The DIN clip arm is configured to attach to a second side of the DIN rail opposite the first side, when in the locked position.

A grounding system for a rackable circuit breaker includes a finger cluster connector connected to a grounding bus in the circuit breaker and a rail conductor mounted in a circuit breaker cradle and connected to ground potential. The finger cluster connector includes a conductor formed from a single plate of conductive material folded into a generally U-shaped body with first and second sides divided into a plurality of fingers. Distal ends of the fingers form mutually facing parallel surfaces of a constricted passage configured to make a sliding electrical contact with the rail conductor that is advanced into the constricted passage as the circuit breaker is racked into the cradle. First and second leaf springs fastened to the conductor portion are divided into a plurality of spring finger sections with spring distal ends configured to respectively press against the distal ends of respective fingers of the conductor portion.

A heater assembly with a pre-encapsulated heating element and a method of producing the pre-encapsulated heating element are provided. The heater assembly can include a channel defining an interior space and a pre-encapsulated heating element. The pre-encapsulated heating element can include a resistive heating element having a pre-encapsulated portion that is surrounded by a block of potting compound. The pre-encapsulated portion can be received with the interior space of the channel.

A mounting kit adapted for a rail component is provided and includes a mounting base, a resilient component and an engaging structure. An accommodating slot is formed on a first end portion of the mounting base. The resilient component is a one-piece structure and detachably and partially accommodated in the accommodating slot. The engaging structure is formed on a second end portion of the mounting base. When the mounting kit is mounted on the rail component, the resilient component is resiliently deformed by the rail component and a wall of the accommodating slot, so as to drive the rail component to engage with the engaging structure along a vertical direction and to abut against a connecting portion of the mounting base for preventing shaking movements of the mounting kit relative to the rail component along the vertical direction and the horizontal direction. Besides, a related rail mounting system is provided.

A carrier-rail bus assembly including a number of n mechanically contiguous bus-circuit-plate sections electrically connected via bus-circuit paths and installed in a carrier rail, an electronic control unit being configured such that it detects whether an apparatus is inserted in an installation position i, respective installation position i being allotted a bus address, which is assigned to the apparatus inserted on the carrier rail on the respective bus-circuit-plate section in respective installation position i. A related method for assigning a bus address is also disclosed.
