PAT testing question

[Daniel Owens]

Hey all
So my boss has got me PAT testing for the firm now but ive a quick question -

A few times when conducting tests on class one equipment ive noticed some slight arcing occur - does anyone else experience this and what is it as it shouldnt happen surely?

Thanks

I assume this is for the earth bond test between the croc clip and connection to the appliance. Ensure the connection is sound and you should not experience this. If your tester is a mains operated unit as opposed to a battery driven one the earth bond can put out 25A on an earth bond test, any loose connection you will experience arcing and inaccurate results.
