[1] General Electric Type I-70 with a cyclometer register is not recommended for use.

 

 

[2] A current transformer type metering device shall not be used in Maryland unless the current transformer used in conjunction therewith meets all requirements specified in IEEE C57.13, Standard Requirements for Instrument Transformers.

 

3 The TRC watt-hour meter may be used only for indoor installation, because the cover of the meter is not rain-tight.

 

4 The current transformers (current sensors) should be installed in a steel, rust-resistant enclosure to prevent unauthorized access to them.

 

5 The UMS watt-hour meter is intended for indoor use only.
