You should choose based on two factors:
-
Voltage Rating: The busbar must be rated for the voltage of the circuit. Note that the allowed voltage may be different for AC and DC.
-
Amperage Rating: Ensure the busbar can handle the total current of all connected devices combined.
-
Number of Screws/Bolts: Ensure there are enough connection points for all the wires in your circuit without "stacking" too many lugs on a single post.
