Buying Guide
When selecting a 150–200 amp meter main combo, consider these factors to ensure the right fit for your electrical service and future needs.
- Amperage and space: Choose a unit that matches your service rating (200A is common for 150A service upgrades) and the number of circuits you plan to install now or later. More spaces allow easier expansion.
- RIngless vs ring-type: Ringless designs simplify wiring and reduce required hardware, but ring-type covers can provide different assembly options. Assess compatibility with your service entrance configuration.
- Outdoor durability: Look for NEMA 3R or better enclosures, corrosion resistant materials (galvanized steel or equivalent), and weather sealing to withstand outdoor environments.
- Neutral and grounding provisions: A fully distributed neutral bar or sub-feed lug options support diverse circuit configurations and solar-ready capabilities where applicable.
- Solar readiness: If solar or future energy expansion is planned, select a unit that supports plug-on neutrals and sub-feed lug kits for straightforward solar integration.
- Rough-in ease: Features like pre-wired lugs, clearly labeled spaces, and organization notches help streamline rough-in work and reduce installation time.
- Brand support and UL listing: Choose reputable brands with robust warranty coverage and UL listings to ensure reliability and compliance with local codes.
