Two electricians are standing on a ladder leaned against a utility pole…

…when an elderly lady was passing below them. One of the electricians calls her.

– Excuse me, ma’m! Could you pass us that wire, so we don’t have to climb down?

– This one, young man?

– Yes, that one! Thank you so much, ma’m, you’re very kind!

– No problem, dear!

After the lady passed him the wire, and left, the electrician tells his mate:

– See, Fred? I told you this was the neutral wire, but no, you had to insist that it was the phase line!
