I'm working a medical project installing a mammogram x-ray unit. On the manufacturer shop drawings it states "Dedicated generator circuit breaker with remote emergency off shunt trip. Provide 3 conductor #10 awg wire from circuit breaker to junction box. Maximum line impedance not to exceed 0.20 ohms for 208V single phase".
Could anyone please clarify what is meant by "Maximum line impedance not to exceed 0.20 ohms for 208V single phase"? Thank you.
