5-7. Line Supply Cable
The Line Supply Cable provides AC power from the hospital Mains Distribution Panel to the Generator.
The Line Supply Cable comprises of two supply wires (FW) and a ground cable (i.e. 3 x AWG 10
(5.32 mm²)) with the following actual/usable lengths:
-
Total length = 7 m (
23’)
-
Usable length = 6.5 m (
21’-4”)
5-7-1.
Obtaining a Line Supply Cable
The Line Supply Cable must be ordered from the price book so that it is supplied with the Senographe
System. Please note that a different price book reference exists for China and the rest of the world.
5-8. Main Circuit Breaker
Circuit breaker sizes for Europe:
•
From 200 V up to 240 V: circuit breaker: In = 32 A (type D) magnetic I = 12In
±20%;
with differential trigger: 30 mA (waveform pulsed).
For circuit breaker sizes and supply conductors for the US market,
refer to Section 517-71(a) and
Section 517-73(a) (Item 1, 2) of NEC-1993 (see below).
•
The branch circuit used must be rated 30 A or less.
•
NEC 1993 Section 517-73 (a) Item 1:
The current capacity of supply branch circuit conductors and the current rating of overcurrent pro-
tective devices must not be less than 50% of the momentary rating or 100% of the long-time rat-
ing, whichever is greater.
•
NEC 1993 Section 517-73 (a) Item 2
:
The current capacity of supply feeders and the current rating of overcurrent protective devices sup-
plying two or more branch circuits supplying X-ray units must not be less than 50% of the momentary
demand rating of the largest unit plus 25% of the momentary demand rating of the next largest unit
plus 10% of the momentary demand rating of each additional unit. Where the X-ray units are used for
simultaneous biplane examinations, the supply conductors and overcurrent protective devices must
be 100% of the momentary demand rating of each X-ray unit.
