Electricity meter forms module
An improved meter base assembly supports the various meter forms used in modern electrical energy distribution systems. The disclosed assembly combines a customized design for each meter form with a universal base used in a plurality of meter forms to create a meter base assembly that is optimized for best performance while maintaining a reduced part cost. In addition, the concept allows the meter terminals to be attached to the meter base assembly without any hardware, may reduce assembly errors, allows for simplified assembly that may be automated, and speeds up the creation of future meter designs.
