What Makes the WEPK4212 Stand Out?

The WEPK4212 is purpose-built for today’s energy demands and inspection standards. Unlike older or lower-rated meter packs, it offers:

  • Higher Load Capacity – Each tenant position supports up to 225A, with a robust 400A main bus.

  • Utility-Approved Design – Fully compliant with NEC 2020 and EUSERC, making it easier to pass inspections and meet utility requirements.

  • Versatile Feed Options – Supports both overhead and underground service entry.

  • Secure Ring-Type Sockets – Tamper-resistant and utility-friendly.

  • No Bypass – Simplified design that prioritizes safety and compliance.

Applications: WEPK4212 vs. WEPK2211

WEPK4212 – Best for:

  • Multi-unit residential buildings (duplexes, triplexes, fourplexes)

  • New developments with high load requirements

  • Light commercial properties

  • Upgrades where future-proofing is needed

  • Projects requiring NEC 2020 and EUSERC compliance

The 4212 is ideal when each unit requires more power (e.g., 225A), such as all-electric units with HVAC, EV chargers, or multiple high-wattage appliances.

WEPK2211 – Best for:

  • ADUs (Accessory Dwelling Units)

  • Small duplexes with limited load needs

  • Garage conversions or backyard units

  • Budget-conscious residential installations

The WEPK2211 is rated at 200A with up to 125A per socket. It's a great solution for low-to-moderate demand setups, such as ADUs or accessory structures where electrical load is minimal but code compliance is still essential.
