Plazma cutter causing SPD failure?? Discussion ThreadPlazma cutter causing SPD failure?? Electrical Advice
I've just had a potentially nasty issue involving a Burnt out, type 2 SPD. My customer has been using a small plasma cutter,
I don't have the exact details of the unit to hand, but it does plug in to a standard 13a socket outlet This is a new 100a single phase TT supply to a small commercial unit.
This was a very close call. The SPD, located directly next to the consumer mainswitch, had burnt out to such a degree, that it has (fortunately) taken out the fuse at the intake.
Is it possible, this cutter could produce enough transient voltage to create this issue?
I was led to believe, these devices should go open circuit when they fail.
