Transformer secondary tap box

[anbm]

Does anyone know who makes 480V, 3PH, 6000A above ground tap box with the connections can be made above ground? ie bring in (10) 4#600KCM to the tap box input terminal and (15) 4#600KCM exit the box. In other word, 4000A input circuit, 6000A output circuit. I have see. a 4000A transformer secondary tap box but all incoming and outgoing feeders run under not above ground…

Hubble / Trinetics makes a few versions like this one with a 4500A rating (which is likely all you need) and can accept a lot of terminations. I'm guessing you are running into this due to derated underground feeders.

Use the front and back of the busbar to terminate up to 40 conductors per phase.

The transformer is existing, we want to have more cables tap to transformer secondary side that it can have, can this box take in and out cables at top or side
not underground, do you know?

I have had equipment manufacturer's service group fabricate lug/termination bussing and enclosures. Custom switchboard people do this all of the time.

What is typical lead time for this type of custom box do you know?

I have no idea, but I am sure it depends on how much you want to pay.
