I recently dug out an old Video8 camcorder, to transfer some 10 - 20 year old tapes to DVD and to hard disk. It's a Sony CCD-TRV11E PAL, if that makes any difference.
The power supply for it is a Sony AC-V16, UK spec, that came with it. The power supply is huge by modern standards, and has a switch on it to switch between using the camcorder and charging the battery. It's rated at 110 - 240V, 50/60Hz, 20W. The output is 7.5V 1.8A to power the camcorder or 10V 1.1A to charge the battery. It has a BS1363/A (standard UK) plug with a 5A fuse, made by Hitachi, moulded onto the cable. The cable is two core.
Anyhow, the battery is almost certainly dead by now, so I was going run the camcorder directly from the power supply. I had the camcorder plugged into the power supply, and I plugged the power supply into a 6-way adaptor (US speak - "powerstrip").
There was a flash and a bang, and half the house went dead.
The damage was the 13 A fuse in the plug for the 6 way adaptor, the 32 A breaker for that part of the house had tripped, and there is a burn mark on one of the pins of the power supply plug.
The 5A fuse in the power supply plug didn't blow. The ELCB (US speak "GFI") didn't trip.
When I had replaced the fuse in the 6-way adaptor and reset the breaker, I went and plugged the power supply into a different circuit, with no 6-way adaptor, directly into the wall.
It worked fine. The power supply also worked fine when plugged back into the 6-way adaptor.
Anyone got any idea what happened?
