66 blocks are designed to terminate 20 through 26 AWG insulated solid copper wire or 18 & 19 gauge skinned solid copper wire. The 66 series connecting block, introduced in the Bell System in 1962, was the first terminating device with insulation displacement connector technology. The term 66 block reflects its Western Electric model number.
Terminal blocks (also called terminal boards or strips) provide a convenient means of connecting individual electrical wires without a splice or physically joining the ends. Since terminal blocks are readily available for a wide range of wire sizes and terminal quantity, they are one of the most flexible types of electrical connector available.
The use of screw terminal "chocolate blocks" in building wiring installations has sharply declined in favour of crimp, push, and twist type connectors which are and easier to fit, and less vulnerable to working loose. In the UK, chocolate blocks are no longer approved for connections that are not accessible for inspection (such as under floors).
PLASTI-GRIP (Vinyl) (insulation restricting) terminals are defined in AMP Specification 114-1003: Terminal, FASTON, PLASTI-GRIP, Application of; UL 310 "Standard for Electrical Quick-Connect Terminals" [4] CSA 22.2 #153, "Quick-Connect Terminals" UL 486 also specifies the testing of standard wire connectors and soldering lugs. MIL-T-7928
Terminal blocks for joining aluminium and copper conductors. The terminal blocks may be mounted on a DIN rail. Aluminium wire was common in North American residential wiring from the late 1960s to mid-1970s due to the rising cost of copper. Because of its greater resistivity, aluminium wiring requires larger conductors than copper.
A 110 punch block. A 110 block is a type of punch-down block used to terminate runs of on-premises wiring in a structured cabling system. The designation 110 is also used to describe a type of insulation displacement contact (IDC) connector used to terminate twisted pair cables, [1] which uses a punch-down tool similar to the type used for the older 66 block.
