Which marking is commonly found on most modern 200-amp electrical meters?

The marking commonly found on most modern 200-amp electrical meters is "200 CL." This designation indicates the "current limit" of the meter, which signifies that it is rated for a maximum continuous current of 200 amperes. This is an important specification because it informs users and electricians of the meter's capacity to safely measure electrical current without the risk of overload or damage.

Markings such as "200 A" might imply the ampacity, but they can lead to confusion since they do not specifically denote the meter's classification in terms of continuous load. "200 M" would generally refer to meter accuracy or type, while "200V" pertains to voltage ratings rather than the current rating of the meter itself. Therefore, "200 CL" is the crucial marking that best denotes the capabilities of a modern 200-amp electrical meter.
