Hello, the chances are that someone has doubled up on conductors to meet the load requirements.Are two of the leads brown/red, and two of them blue/black?
You had an electrician there?!! And they didn't know how to do this?I'm gobsmacked. I would ask them not to come back.There's only one safe way forward.1. Isolate the power at the consumer unit MCB for this circuit.I would expect the MCB to be a B40 breaker.2. Remove the accessory screws from the flex outlet.3. Examine the conductors connected behind the flex outlet - you will then know which connect to the supply live and neutral.4. To be extra safe, check the polarity of the conductors coming to the flex outlet.
