Power Distribution Blocks
What Is A Power Distribution Block?
Power Distribution Blocks provide a method of managing electrical wires and splitting input power across several electrical circuits. We offer finger safe and open style Power Distribution Blocks. This selection includes three different open style size varieties. Power Distribution Blocks are available in 1 to 3 Poles.
Where Are Power Distribution Blocks Used?
Power Distribution Blocks are general purpose and are used in control panels when it is desired to power multiple devices with a single input. As such, they can see use in virtually any application with a control panel.
Who Uses Power Distribution Blocks?
Due to their widespread use in control panels, a wide variety of industries make use of power distribution blocks. Some examples include:
- Industrial Control
- Material Handling
- Power Generation
- Food and Beverage
- Heating and Air
- Building Control
- Solar
- Mining
How Many Poles?
To begin selecting your PDB, first you must know how many poles you need based on input power. For example, you may need three poles for your three-phase input. Our power distribution blocks are available with 1, 2, or 3 Poles.
How Many Input and Output Holes?
The number of holes is listed per pole. For example, you might have two poles but split the capacity between four lines per pole, and for this you would require four line side (or input) holes. The same is true for load side (output) holes.
How Many Amps?
The PDB you choose should meet or exceed your amperage needs. Selecting a PDB with an amp rating below your requirements may cause damage to the power distribution block and is a fire risk.

What Wire Size?
Wire size is an important metric that will be the final determination of what PDB you choose. The PDB must accept the wire you are using, and ultimately you can use a power distribution block with more holes than you need so long as the amps and wire size meet your needs.
