In a car tyre fitters!
As a UK ring main can supply 32A the UK plugs rely on the inbuilt 13A fuse for protection!
So these cheap Chinese plugs (lower black) can cause fires 🔥🔥🔥🔥🔥!
I guess to lazy to add a plug to the end of the lead!
Someone got a shock while changing the bulb in this fluorescent fitting!
Turn off before changing the bulb or starter!
