Any capacitor placed across a power line must be UL/CSA rated
for line-bypass applications. The components are clearly marked
with AC voltage ratings, and have UL/CSA and perhaps VDE logo's
Remember all those TV set fires in the 60's and 70's? Many were
caused by power line bypasses. Normal disk capacitors will flame
up like a torch if they short, and shorts are common because of
line transients unless the capacitor is rated at well over 1kV dc.
Whatever you do, small capacitors like that are a source of great
heat if they fail. Be sure you have a proper flameproof enclosure
and use the proper capacitor for line-bypass!!!
I've had success using .01uF 250VAC rated capacitors, in
conjunction with ferrite beads over the leads arriving at the box, to
tame my motion detecting lights.
