Buying Guide: Key Considerations for 100 Amp Meter Sockets With Main Breakers
- Main breaker presence: Decide if the main breaker is required inside the meter socket or if it will be separate. Some enclosures are designed to accept an external main breaker, while others come as “main breaker not included.”
- Delivery environment: Choose indoor, outdoor, or weatherproof ratings (NEMA 3R, etc.). Outdoor installations benefit from corrosion resistance and secure mounting.
- Number of spaces and circuits: If you need room for future expansion, select models with additional spaces and compatibility with plug-on surge protectors or additional breakers.
- Compatibility and code compliance: Verify that the chosen unit is UL-listed and compatible with common breakers (Homeline, Siemens, etc.) and your local electrical code requirements.
- Connection type: Ring-type vs. ringless sockets affect installation and maintenance. Ring-type often provides robust contact and sealing, while ringless designs can be easier to install in tight spaces.
- Safety features: Look for tamper resistance, secure lugs, ground lug options, and horn bypass where applicable to improve safety in outdoor or accessible locations.
- Brand and support: Reputable brands (Siemens, Square D, Midwest, Eaton) typically offer better compatibility with standard breakers and easier parts sourcing.
