Blocks mount in a cutout and have terminals on both sides.
Terminal block wiring definition.
Inspect the terminal block and wiring without opening the cover.
This terminal is connected to the female port on the terminal block and forms a secure connection.
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.
Terminal blocks are used to secure and or terminate wires and in their simplest form consist of several individual terminals arranged in a long strip terminals are useful for connecting wiring to a ground or in the case of electrical power for connecting electrical switches and outlets to the mains.
When purchasing a terminal block barrier strip or wiring it is important to note the type of block required connection type the number of contacts and contact pitch wire gauge and entry angle and the voltage and amperage ratings of the product.
Plug in blocks are commonly used in the fuse boxes of automobiles.
We offer four types of nema terminal blocks.
Tiers may be bridged creating four common connections.
Push in terminals allow you to connect a wire simply by inserting it most push in terminals require the use of a ferrule.
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.
However some push in terminal blocks allow to insert a solid conductor directly or a stranded conductor by inserting a screwdriver into the release hole.
A ferrule strengthens the end of the wire conductor.
Nema terminal blocks offer easy wiring with standard size screwdrivers easy visual verification of proper wire position and easy marking.
Led neon indicating lamps diodes and resistors available.
Type of basic terminal block used for wire to wire connections where the wire feeds through one side and out the other.
Most of our nema blocks are available pre assembled on a breakaway mounting channel complete with one end anchor retaining clip and one end barrier.
Dual level feed through figure 14 two level feed through in one block.
