    4-way extension with trunked flex

    I was chatting with a PAT tester who mentioned that he would fail 4-way extensions where the flex had been trunked and the client was using them with appliances drawing 13 amps. His reasoning was that the trunked flex should be de-rated. Would you agree with this?
