Electric shock from cooker hob when holding iPhone while charging!

[Adee]

Hi

Maybe a bit of a weird one, but when charging a iPhone from either socket beside our stainless steel cooker gas hob, if you hold the phone in one hand and touch the gas hob with the other, you get a little tingling electric shock, like a static shock, but it's continuous.

I have tried different usb chargers and one of the sockets has USB ports but the other socket is a standard double MK logic.

I have checked that all sockets and hob are earthed, which they are.

Any ideas why this is happening?

How did you do this test / check?

Hi

i used a socket tester in the sockets and a meter in continuity mode from the cooker hob plate to a earth on a socket box.

that does not prove anything

Ok doesn't it prove that at least the hob is connected to the earth?

I will book a electrician to get it check out!

there is a lot more to it than simply stocking a meter between 2 unknown points

All it proves is that they are connected together (to some degree),,, it does not prove that either of them are earthed

Are you charging from a USB slot built into a socket? Or using a cheep charger. 

The 5V side of the charging circuit is often poorly isolated from the mains with cheep USB equipment.

Hi

I have tried both USB built into socket and 240v to 5v usb apple IPhone genuine charger.
