A test system and method for relay connection and testing of a power transmission and distribution grid including a fixed connection block connected to the power transmission and distribution grid, and a mobile plug which connects the fixed connection block or a mobile test block with the relay when the mobile plug is inserted into the fixed connection block or the mobile test block. The mobile test block provides a connection to an external relay testing device when the mobile test plug is inserted into the mobile test block, the fixed connection block provides internal shorting that is activated when the mobile plug is not inserted into the fixed connection block and is deactivated when the mobile plug is inserted into the fixed connection block, and the fixed connection block, mobile plug, and the mobile test block provides an interaction between a power transmission and distribution grid side and a relay side. This allows a quick recovery when relays are damaged in a cyber-attack.

In an embodiment, a battery connector includes: power terminals configured to be coupled to a load having an input capacitance; power pins electrically coupled to the power terminals; a charge pin, the charge pin being longer than each of the power pins; and an antispark circuit electrically interposed between the charge pin and the power terminals, the antispark circuit including: a dissipation circuit configured to charge the input capacitance of the load in response to a battery being coupled to the charge pin; and a delay circuit configured to delay charging of the input capacitance of the load for a predetermined duration after the battery is coupled to the charge pin.

A terminal block structure and an unbuckling unit thereof are disclosed. The unbuckling unit has a base member and a rotary member, the rotary member is connected to the base member to be operated. The rotary member includes a first arm part, a second arm part extended from the first arm part and a rotary part disposed between the first arm part and the second arm part. The second arm part has a buckling unit, and the rotary part is connected to the base member. When the first arm part is applied with an external force, the rotary member rotates about the rotary part as a rotation center to drive the second arm part to ascend. Accordingly, advantages of easily to be pressed and operated, simple in structure and convenient to be assembled are provided.

The Knee Saver Multiplex Electrical Termination Device Board is comprised of; a one-piece board, consisting of a combination of several alike/or unlike termination devices, where multiple termination devices are within a single enclosure, which can handle more than one power source, with different amperages, at the same time, and used in conjunction with the Knee Saver U.S. Pat. Nos. 9,960,580, 9,368,948, 10,320,169, and patent application Ser. No. 16/214,239 which is installed, into a single HUB or Dielectric body, without the need to get down on your knees to install receptacles.

A distribution block for attaching to a support rail extending in a support direction comprises an insulating housing, and a conductive member arranged in the insulating housing. A mounting assembly of the distribution block is connected to the insulating housing for attaching to the support rail. The distribution block is mountable on the support rail in a longitudinal configuration wherein the extension direction of the insulating housing is substantially parallel to the support direction, and in a transverse configuration wherein the extension direction of the insulating housing is transverse to the support direction.

A bus device of a terminal block includes a case and a latch assembly. The case has a connecting side and is formed with a sliding trough. The latch assembly includes an actuator and a locking peg. The actuator is disposed in the sliding trough and movable along the sliding trough between a release position and a locking position. The actuator has an actuating ramp set. The locking peg is axial-rotatably disposed in the case and arranged corresponding to an end of the sliding trough. An end of the locking peg projects from the connecting side and has an inverted hook. The locking peg has a protrusive key abutting against the actuating ramp set. When the actuator moves between the release position and the locking position, the actuating ramp set is configured to push the protrusive key to axially rotate the locking peg.
