- f4 ^6 l2 H( w) FAccessible conductive parts separated by double or reinforced insulation, e.g. live parts and the body or primary and secondary circuits, may be bridged (conductive bridged) by resistors or Y2 capacitors provided they consists of at least two separate components of the same rated value (resistance or capacitance), each rated for the total working voltage and whose impedance is unlikely to change significantly during the individual lifetime of the luminaire. If the working voltage does not exceed the rated voltage of the capacitor, accessible conductive parts separated by double or reinforced insulation from live parts, as above, may be bridged by a single Y1 capacitor.

Y1 or Y2 capacitors shall comply with relevant requirements of IEC 60384-14 and if resistors are used they shall comply with the requirements of test (a) in 14.1 of IEC 60065:2001, Amendment 1:2005. ; e7 ^4 t$ L9 |" y
