Fluorescent Tube Question.

How did you find out it creates a dead short?

How did you find out it creates a dead short?

The new L.E.D. tube came with no instructions at all. I had an instruction sheet from a 4ft tube though that explained that the supply is from one end only. I referred to that after having trouble with the B6 M.C.B. tripping off. The two metal dummy pins are connected together on the 5ft tube as confirmed by an Ohmeter. The feed end  is marked on the tube end but is only in small print. Having accidently fitted the tube the wrong way round I tripped off the B6 M.C.B. I think that the design of the tube is dangerous and bad. The two dummy pins could be separated and not shorted together. A very poor design. Also, it is possible to fit a new tube wrongly as the live end cap of the fitting is not identified. I prefer the new L.E.D. tubes with the replacement fused "F.S.U." These require no internal alterations of the old fitting's internal wiring.

the idea is to put L to one end, neutral to the other and short the starter

No. The instructions that I eventually found in a 4ft pack of the same maker's 5ft tube called for a single feed at one end only.
