Two weeks after completing a house rewire customer calls me on a Sunday morning. "Every time my husband puts the toaster on it trips the rcd. And its a new toaster from Argos, only 2 weeks old. We didn't have this problem before you put in those rcd things!"
So I went through the process. Have you had any work done? Have you put a nail/screw into a wall? Have you plugged an outside appliance from the kitchen (eg extension cord, light etc.
"No, we've done nothing and my husband wants his toast, he has toast every day so this needs sorting out!"
I'm the kind of man that will go out on a Sunday morning FOC to see if its anything to do with me. Not happy about going out to it, its a 25 mile round trip and me and the wife have got plans for the day. Oh well.
Just before I was about to end the call and say I'll be with you within an hour I asked "have you dropped the toaster? Water got inside? Changed the plug? (husband is a DIY disaster type of man).
"Oh" she says, "might it have anything to do with my husband getting a piece toast stuck yesterday and trying to get it out with a metal knife? He didn't half get a shock from it!"
Thank god you've now got rcds and not a BS3036 board. Anyway whilst laughing to myself I told her to go back to Argos and get it replaced and call me when he makes his toast in the morning, I'm off to the seaside now.
Call in the morning, everything is fine with the new toaster and apologized for calling me on a Sunday when it was his fault. So far from them recommending me I've had a kitchen rewire and a cu change. Told her if she gets me one more cu change I'll buy them a new toaster plus a loaf of bread as a thank-you. That man loves his toast lol.
