FAQs
Yes. The U121315 is a side-mount, 1-pole meter socket rated for 100A and designed for standard #14-2/0 line and load conductors. Its five-jaw ring-type contacts and ring cover simplify termination in confined spaces while maintaining code-compliant clearances. When retrofitting, verify panel interior dimensions and clearance for the 4.625 in depth and 17 in height to ensure a clean installation with accessible terminations.
Key specs include 100A amperage rating, 1 pole, 3-wire configuration, and five-jaw ring-type connections with #14-2/0 line/load lugs. It uses steel construction with ANSI 61 paint finish and UL Listed certification, providing durable service in commercial and light-industrial applications. Confirm compatibility with your service entrance and conductor sizing per local codes before procurement.
The unit is ideal for commercial and light-industrial power distribution requiring secure, durable metering enclosures. Its steel body with ANSI 61 finish resists corrosion in moderately harsh environments, and the side-mount design suits equipment racks and compact service rooms. It’s well-suited for new builds and retrofit projects where rapid installation and reliable terminations are priorities.
The U121315 carries UL Listed certification, providing assurance of compliance with recognized safety standards for meter sockets and metal enclosures. The ANSI 61 paint finish reflects adherence to widely accepted finishing standards for electrical equipment, contributing to durability and corrosion resistance over the product life cycle.
Its rugged steel construction, secure five-jaw connections, and ring-type cover reduce termination looseness and related faults, lowering maintenance calls and unplanned downtime. The side-mount design simplifies installation, helping projects stay on schedule and limits field labor costs. Additionally, the 100A rating aligns with common service upgrades, supporting scalable future-proofing.
