For the type A events the 0.5 fuse will open, providing non-operational compliance. The 1.25 & 2.0 will not open, providing
for operational compliance with TIA-968-A type A surge events.

Selection of test number depends on current limiting & fire enclosure/spacing of
end product
• 26 AWG line cord removes L1/M1 test requirement
• L5 conducted only if product does not pass section 6.1.2
• L2,M2,L3,M3,L4,M4 conducted if not in a fire enclosure
Fuse must open before the wiring simulator fuse (MDL 2.0).
