◆ Easy to install with their split-core design
◆ Can be field-installed inside distribution and control equipment such as switchboards and panelboards, or used in equipment designed for MV / LV substations, power quality meters, energy meters, branch circuit meters, PV monitoring, motor quality diagnostics, traction and data center use, etc.
◆ Install in accordance with ANSI/NFPA 70, “National Electrical Code” (NEC). Follow all local electrical codes.
◆ Only qualified personnel or licensed electricians should install the current transformer (CT). Line voltages of 120 Vac to 600Vac can be lethal.
◆ Do not install CTs where they block ventilation openings.
◆ Do not install CTs in the area of breaker arc venting.
◆ The current transformer cannot measure direct current (DC), and excessive DC will degrade AC measuring accuracy.
◆ Electrical codes prohibit installation of CTs in equipment where they exceed 75% of the wiring space of any cross-sectional area.
◆ The PQ-CT lead wires are considered Class 1 wiring (as defined by the NEC) and must be installed accordingly. They are not suitable for Class 2 wiring methods and should not be connected to Class2 equipment.
◆ If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
◆ Do not install the CT where it may be exposed to: temperatures below -40°C or above 70°C (-40°F to 158°F), excessive moisture, dust, salt spray, or other contamination.
◆ The PQ-CT may be damaged if dropped or subjected to impact. This can result in reduced accuracy.
