Power Distribution Block 620 A Copper

The Bussmann 16500-1 is a single-pole power distribution block rated for 620 A with copper conductors. It accepts copper or aluminium wire from 6 AWG up to 350 kcmil on both line and load sides, providing two connections per pole. The open-design unit mounts on a surface and operates at up to 600 V with an overall depth of 2.89 in.

Suits single-pole high-current distribution

This block suits panels that need to split or join heavy copper feeds in a single-pole arrangement. It is not for installers who require multiple poles in one housing, or for systems that demand a higher voltage rating than 600 V. Buyers needing integral stud terminations or a different mounting style should look at other configurations.

620 A copper rating decides fit

The 620 A maximum current with copper conductor is the figure that determines whether this block matches the load. If the circuit calls for a higher ampacity or a lower maximum wire size, another block must be chosen.

Questions about this item

How do I install the 16500-1 block and which step is commonly missed?

Surface-mount the single-pole block, then terminate up to two line and two load conductors per pole in the 6 AWG to 350 kcmil range, torquing each set-screw to the manufacturer's specified value — the step often skipped is verifying torque on every connection.

What maintenance or replacement will the 16500-1 block need over time?

Periodically inspect all set-screw terminals for discoloration or looseness and re-torque to spec; replace the block if any connector shows heat damage, cracking, or can no longer hold 6 AWG to 350 kcmil conductors securely.

At sustained loads, what limit of the 16500-1 block is reached first?

The 620 A copper-conductor rating is the first hard limit; continuous operation above that current will overheat the terminals before the 600 V insulation rating becomes a factor.
