Milbank K3388 – Frequently Asked Questions

1) What size opening does the Milbank K3388 test switch cover fit?
The K3388 cover measures 3.149 x 9.813 x 4.437 inches overall, with the 9.813 inch dimension listed as the width and 4.437 inches as the height. Take those numbers against the test switch cutout in your meter enclosure before ordering, since the cover is sized to the switch opening, not the enclosure.
2) What is the difference between the clear K3388 and the K3388-BLK-FL?
Both are the same Milbank test switch cover; the choice is the finish. The K3388 is clear, so a technician can see the switch position without pulling the cover. The K3388-BLK-FL is a black flush version, which hides the switch and sits flat to the panel face. Utilities and facilities that want visual verification during testing usually take the clear.
3) What material is the Milbank test switch cover made from, and will it hold up in a meter room?
Polycarbonate, unpainted. That gives impact resistance and a non-conductive barrier over the test switch, and because there is no paint film there is nothing to chip or flake off inside the metering compartment over time.
4) Can I order the Milbank K3388 cover as a replacement part on its own?
Yes. The K3388 is sold as a standalone metering accessory, so it can be ordered to replace a cracked or missing test switch cover without touching the switch or the enclosure. Order by MPN K3388 for clear or K3388-BLK-FL for black flush.
5) Where is a test switch cover like this actually used?
On metering installations where a test switch needs to be shielded but still reachable: utility service equipment, commercial meter stacks, industrial power monitoring, and multi-family meter banks. The cover keeps hands and tools off the switch terminals during routine work in the metering compartment.
6) Does the Milbank test switch cover come with mounting screws?
Mounting hardware is not itemized for the K3388. It is a sheared polycarbonate cover, so plan on reusing the existing fasteners from the switch or panel it mounts to, and confirm you have them on hand before the truck rolls.
