QUAZITE
Frequently asked questions
Common questions about QUAZITE from 3G Electric.
What are the standard sizes available for QUAZITE underground electrical enclosures?
QUAZITE underground enclosures come in a range of standard sizes, typically defined by the opening dimensions and usable interior depth. Common opening sizes include 11 in x 18 in, 13 in x 24 in, 17 in x 30 in, and 24 in x 36 in. Usable interior depths range from 16 in to 28 in or more. The part number often indicates the series; for example, PG1118 corresponds to an 11 in x 18 in opening, PG1730 to a 17 in x 30 in opening, and PG2436 to a 24 in x 36 in opening. The covers are matched to the enclosure opening size. When selecting a size, consider the volume required for splices, the number and size of conduits, and the depth needed for equipment. 3G Electric lists specific SKUs with their dimensions to help match existing installations.
What material are QUAZITE enclosures made of and what are the benefits?
QUAZITE enclosures are made of polymer concrete, which is a mixture of aggregate and a resin binder. This material offers high compressive strength, resistance to freeze-thaw cycles, and resistance to chemicals and road salts. Unlike metal enclosures, polymer concrete does not rust or corrode, making it suitable for wet or corrosive soil conditions. It is also non-conductive, which can be an advantage for electrical applications. However, polymer concrete is heavy, so installation typically requires lifting equipment. The material can be molded into complex shapes, allowing for monolithic construction with an open bottom for cable entry. The covers are also made of polymer concrete and are designed to withstand loads when properly installed.
How do I select the correct QUAZITE cover for my enclosure?
To select the correct QUAZITE cover, you need to match the cover to the enclosure opening dimensions. The cover must fit the opening length and width exactly. For example, a cover for a 17 in x 30 in opening will have a part number like PG1730HH0017, where the first four digits indicate the opening size. The cover also includes a logo, typically Electric, to indicate the enclosure's purpose. You should also consider the load rating required for the installation; covers are available in different load classes for pedestrian or vehicular traffic. Ensure the cover is compatible with the enclosure body, as some enclosures may require specific cover styles. 3G Electric's product listings include the opening dimensions and manufacturer part number to help you match the correct cover.
What is the purpose of the Electric logo on QUAZITE covers?
The Electric logo on QUAZITE covers is a standard designation that identifies the enclosure as part of an electrical system. This helps utility workers, maintenance personnel, and inspectors quickly identify the enclosure's contents and avoid confusion with other underground utilities such as water, gas, or telecommunications. The logo is molded into the cover during manufacturing, so it is permanent and will not wear off. In some jurisdictions, marking electrical enclosures is required by code to ensure safety and proper identification. The Electric logo is available on many QUAZITE covers, and it is specified in the part number or product description. When ordering, confirm that the cover includes the desired logo.
Can QUAZITE enclosures be used in areas with vehicular traffic?
QUAZITE enclosures and covers are available in load ratings suitable for various applications, including areas with vehicular traffic. The load rating depends on the specific cover and installation. For example, covers rated for incidental traffic (such as driveways or parking lots) are different from those rated for heavy traffic (such as highways). It is important to select a cover with the appropriate load rating for the intended location and to ensure proper installation, including a stable base and backfill. The polymer concrete material has high compressive strength, but the cover must be matched to the load requirements. Consult the manufacturer's load rating tables and local codes to determine the correct product for your application. 3G Electric can provide specifications for specific SKUs.
What is the difference between an open-bottom and solid-bottom QUAZITE enclosure?
An open-bottom QUAZITE enclosure has no floor, allowing cables and conduits to enter from below and providing drainage. This design is common for underground electrical distribution because it prevents water accumulation and simplifies cable installation. A solid-bottom enclosure has a floor, which may be used where a dry environment is required or where the enclosure is installed above grade. Open-bottom enclosures are typically placed on a bed of gravel or crushed stone to facilitate drainage. The choice between open-bottom and solid-bottom depends on the application, soil conditions, and whether water ingress is a concern. The sample products from 3G Electric are all open-bottom models, but other configurations may be available.
