Q
What is wire diameter that allows installing a current sensor?
The nominal cross-sectional areas of the conductor of 600-V vinyl coated wires that can

The above shows the standard nominal cross-sectional areas. Due to the outer difference of
A
finished vinyl insulation and deformation (bending) depending on manufacturers, a wire may
not penetrate.
Make verification on site.
Q What are the points when installing a current sensor?
Models EMU2-CT5, EMU-CT*** and EMU-CT***-A are split-type. If split surfaces are not
