Why no BIL ratings for Ansi Low Voltage Switchgear?
Why no BIL ratings for Ansi Low Voltage Switchgear?
(OP)
Just curious on this, how come ANSI doesn't reference any tests for impulse withstand on low voltage switchgear?
I can see that LV switchgear won't typically be exposed to lightning, but how about switching surges?
