Compliance West’s line of Leakage Current Networks are built in accordance with IECEE OD-5013, “Leakage (Touch) Current Measurement Instruments”; and are in compliance with IECEE OD-5014, “Instrument Accuracy Limits, specifically “Leakage (Touch) Current” Section; and UL 763. Our Leakage Current Networks use very accurate components which do not drift due to heat or age, and we specially trim each component in each leakage current box we make to be accurate. In the case of the UL Leakage Current Network, we test the devices to be accurate to 5% from dc to 100kHz, and use metal enclosures to minimize interference.
Resistors and capacitors have a tolerance of ±1%, verified during the calibration process.
All components used are designed for low parasitic inductance and capacitance, and the physical layout of the components is optimized for higher frequencies.
The metal box and ground plane of the circuit board are joined via solid contact to provide shielding of the network, and leads are shielded.
Calibration procedure to allow A2LA calibration from dc to 100kHz is included, enabling any lab with sufficient scope to perform.
Each box ships with the Leakage Current Network embossed on the front panel. Leads provided are alligator clips, and they can be changed to any desired configuration by the operator in the field.
