I've just finished a part rewire of an estate agents shop/office, part of the spec was to give the window display guys a feed via 2 x DB sockets for their LED window display as below.
Each column is on its own driver via a plug from my supply. The supply is from a 2.5mm on a Squre D C16 MCB, (SQO range btw) clipped direct and trunking (enough info for you guys )
Owner of the estate agents has just called me now saying that one column went off yesterday and that the other two went off today at different times! I told him that it will be the drivers of each unit, they have a thermal cut off switch and it must have kicked in. But the window display man (owner of the company) says it isn't!!! They have never had this problem before and it must be the electricians fault!!!!! We will see on Monday. The MCB has not tipped, all tests are great (new circuit). It must be his equipment that he has plugged in?
That is my question. How do I prove that it is his drivers at fault??? I may ask Test-Meter to loan me a thermal camera and take readings at different times of the day of the drivers.
Any help on this will be great lads, thanks in advance.
btw I will be telling the window display guy to go and multiply on Monday, should be an interesting conversation :6:
