4. ELECTRICAL LINE REQUIREMENTS
a. The electrical line must be "single-phase" type
b. It is essential that a 16A – 250V, magnetothermal differential switch be fitted
upstream of the X-ray system, with differential protection In<= 30mA
(refer to §20 “ATTACHMENTS”)
c. The power cords of the timer and the tubehead connection conductors with must be
two-pole + ground, and in proportion to the length of the power cord, as shown in
