NO switch insulation resistance failure

[sysrq]

How often do we usually have insulation resistance failures on an NO switches leading to unexpected starts?

dunno about that, but i get insulation failures in my underpants leading to unexpected farts.

when was the last gas safety check done on that Tel!

Can you explain what you mean.

How often do we usually have insulation resistance failures on an NO switches .....

Are they IP rated for the environment... Too vague ..
Regular testing , inspection regime , old reliable /any equivalent replacements fitted ....many things to consider
( the propper answer would be by a paid report ! )

I don't understand where insulation resistance fits into a NO button failing

Is this a college question?

Baffled!

No, from a real world experience.

When the voltage is high enough some leakage current develops between the terminals.

No, from a real world experience.

Oh.......I thought you meant normally open..

 

[buzzlightyear]

No, from a real world experience

please explain?

How High does the voltage have to be? I presume more than 400v

Don't know the exact voltage this time but sometimes 24 V is enough.

Pardon?
