What does a distribution block do?
A Distribution block is an economical and convenient way of distributing an electrical circuit from a single input source, to several devices in the branch circuit. Thus re- ducing the total number of wires in your electrical panel and saving you time and money.
Where do I install distribution blocks?
Power distribution blocks are only permitted to be installed on the line side of service equipment.
Can you use a distribution block for grounding?
it is ideal to ground to the same spot (using a distribution block). this helps avoid a voltage potential between seperate grounds which in turn can induce alternator whine into the system.
