Hubbell Wiring PG1730BA30 – Frequently Asked Questions

1) Does the Hubbell Quazite PG1730BA30 underground box come with a cover?
The PG1730BA30 is the box body only. It is a PG style enclosure built to work with Quazite covers, extensions, and accessories, so the cover is a separate item you order to match the opening and the load rating you need. Plan the cover into the same order, or you will have an open vault sitting in the ground.
2) What does Tier 22 mean and can I put this box in a driveway or roadway?
Tier 22 is a below-grade load classification for pedestrian and light-duty non-deliberate traffic areas, and the PG1730BA30 is built as a Tier 22 standard box for underground electrical, telecom, and utility vault work. It is not a traffic-rated vault. If the box lands in a driveway, parking lot, or roadway where vehicles will run over it, you need an enclosure and cover rated for that traffic, not a Tier 22 box.
3) Why choose an open-bottom underground box instead of one with a closed base?
An open bottom lets water drain straight into the native soil and gives you free access for cable entry, routing, and splicing from below, which is why it is the common choice for utility and telecom pull boxes. Pick a closed-bottom enclosure instead when you need the box isolated from groundwater or you are mounting equipment to the floor of the vault. The PG1730BA30 is the open-bottom configuration.
4) What is the exact part number to order for this Hubbell Quazite box?
Order Hubbell Wiring PG1730BA30. That is the open-bottom Quazite polymer concrete box, Tier 22, measuring 19-1/4 x 32-1/4 x 30 inches. The PG prefix identifies the box style, so quote it exactly when matching covers or extensions to it.
5) Is polymer concrete better than precast concrete or steel for a buried pull box?
Polymer concrete is non-conductive and resists corrosion, cracking, and the chemical exposure you get in buried environments, which is the main reason it is specified over metal or traditional concrete below grade. It is also lighter to set than precast concrete of the same size. The Quazite polymer concrete body on this box is the same material standard used across electrical, utility, and telecom work.
