A meter socket base is a standard electrical fitting designed to securely accommodate an electricity meter. It also provides a sturdy, weatherproof connection point for the incoming service power cables running into your property.
Most models come as a metal enclosure fitted with a hinged cover, and they are generally installed on the exterior wall of a building right beside the main power service entry point.

Customization
We understand that every project may have unique requirements. Our 100A meter sockets offer customization possibilities as follows:
Color Customization
While the standard baked gray powder polyester paint provides excellent corrosion resistance, we can customize the paint color to match your project's aesthetic or branding needs. Whether you need a specific shade to blend with the electrical panel's surroundings in a high-end commercial space or a color that aligns with your home's exterior theme, we are able to accommodate such requests.
Terminal and Wiring Configurations
Depending on your specific electrical system setup, we can customize the terminal types and wiring configurations. If you have special requirements for wire connections, such as unique terminal sizes or arrangements for easier installation in a compact electrical panel, our team will work with you to create a tailored solution.
Conduit Hub Adaptations
If your project requires non-standard conduit hub sizes beyond the 1" to 2 - 1/2" range, or specific hub designs for specialized conduit systems, we can customize the meter socket to fit. This ensures seamless integration with your existing or planned conduit infrastructure.
Enclosure Customization
We provide comprehensive custom sizing services for meter sockets. Based on your drawings, load specifications and on-site installation conditions, our technical team develops meter bases with custom length, width and depth, alongside optimized internal wiring space to fit your exact project specifications.

A: Yes. We employ a seasoned professional team with abundant expertise covering the full cycle of electrical enclosure design, development and manufacturing.
Q: 5. Do I need a licensed electrician to install it?
A: Yes. Improper wiring poses safety risks and may not pass local electrical code checks.
Q: 6. Can meter base be mounted flush against exterior walls?
A: Pre-punched mounting holes on the rear panel allow flush surface mounting on brick, wood, concrete and vinyl exterior walls..
Q: 7. Can I upgrade from a 100A socket to a 200A socket without changing the service entrance cable?
A: No. The meter socket rating must match or exceed the service entrance cable rating and the main breaker rating. If you are upgrading your service amperage, the entire system-including the service entrance conductors (SEU/SE-R cable) and the main distribution panel-must be evaluated and likely upgraded by a licensed electrician to handle the increased load safely.
