Buying Guide
What to consider when choosing a 100 amp meter box:
- Installation environment: Indoor, outdoor, or damp locations require different enclosures (IP ratings, weatherproofing).
- Mounting and access: Wall-mount vs. pedestal, back panel design, and service accessibility.
- Electrical compatibility: Ensure meter socket type (4-jaw vs. ringless) matches your meter model and feed configuration (overhead/underground).
- Materials and durability: Copper interiors provide better transmission; steel externals offer rugged protection and longer life.
- Safety and standards: Look for ANSI C12.7 compatibility and any local utility acceptance requirements for installation.
- Size and layout: Consider physical footprint, knockouts, and clearances for wiring and future expansion.
FAQs
- What is a 4-jaw meter base good for?
It securely holds standard plug-in meters and supports stable current transmission for most residential setups.
- Is a horn bypass feature necessary?
Horn bypass allows the meter base pathway to bypass the meter horn, useful in certain testing or maintenance scenarios.
- Can these be used outdoors?
Many are designed with weatherproof or heavy-duty steel housings, but always verify IP ratings and installation guidelines.
- Do I need a professional for installation?
Meter socket installation often involves utility coordination and electrical codes; consult a licensed electrician if unsure.
- What should I check with my utility before purchase?
Confirm acceptance requirements, meter compatibility, and any local service connections needed for your property.
- Are copper interiors essential?
Copper components generally offer better conductivity and reliable transmission than alternatives, especially at higher loads.
