Don't ever leave your layout under power if you're not in the train room! Call me paranoid...but my boss used to say "Only the paranoid survive..." Cheers

My pet hate is people leaving phone chargers permanently plugged into the mains. Although they have been making them much safer over the years there is always the risk that they can go wrong when there is no-one around.

Your layout transformers should be plugged into a protected power strip and that is how you make sure everything is powered off.It's called a switch. D

I always unplug my layout from the mains supply whenever it is not in use. A friend in our Marklin Club who had a large H0 layout (900 sq ft) had a lightening strike on his house, which cooked his 6021 / 6051 controllers / boosters and rendered the layout inoperable until they were replaced / repaired. The same person is now building a large G1 layout (22m x 10m) in a purpose built basement, and that room has surge protectors installed on the mains outlets.

Agreed, and not only is there the risk of failure, but you have all these millions of chargers, plugged in, consuming a small amount of power each, doing nothing other than generating heat, and we seem happy to pay for it. I'm guilty of it as well, but we do have most of the phone/ipod chargers on one strip so when they are not in use they can be all turned off and you can easily see the consumption drop in the power meter.

The insulating materials from that era were notorious for falling apart with time. No-one in his right mind should use one of these except in the most carefully monitored conditions, and even then with a master off switch very easily to hand and a fire extinguisher ready! Old trains will run just as well with a modern transformer to provide the power. Safety first!

Joined: 16/08/2006(UTC) Posts: 5,382 Location: Akershus, Norway		A small warning in our washing room, we have a rechargeable vacuum cleaner in a holder on the wall. It is charged by a small 12volt power supply, more or less permanently connected in the 230 Volt wall outlet. One day, passing it on the way to my train room, I detected a burnt smell. I noticed that the power supply's white housing suddenly was light brown. It was too warm to handle, so I used some kind of tool (cannot remember what) to pull it out of the wall outlet. I cut the wire and threw it all away (after cooling down) Before connecting anything to the wall outlet, I will install a switch. All my MMR power is connected via a central switch. We have three smoke detectors connected via our alarm system.

Joined: 23/03/2012(UTC) Posts: 2,550 Location: Finland		Thanks to all from warnings. I just went to train room and unplugged my rechargeable vacuum cleaner and iPad chargers... But also my layout power, CS2 with transformer, separate transformer for layout lights and accessories + one transformer for my Märklin My World series signals are all connected to a central switch before wall socket. My stereos below my layout are also connected through a different switch to other wall socket, but that switch is in very difficult place and I don't turn it off. Maybe I should, but I have never heard of an stereo amplifier or cd player to cause a fire... Janne Edited by user 17 March 2014 12:49:20(UTC) \| Reason: typo newer => never

I have heard of instances where an amplifier caught fire, but this is a very very rare occurrence. Many high quality amplifiers are made to be on all the time, as the continual thermal stress of powering on and powering off can cause output transistors to blow - especially if the amplifier has a high inrush current when turned on.

I remember we used to leave our amplifiers the school hall on for a whole term at a time! We only ever turned the off in the holidays, if we actually remembered to! Someone used an isolating transformer to try and reduce the impact of a ground loop with the projector one day and it worked. A few months later we borrowed one from the woodwork room, we had some All Blacks visiting for the rugby world cup and we wanted to try and stop the flickering picture. It tripped almost every circuit breaker in the hall and we were expecting 1200 people to arrive in 5 minutes. It was the first time the amplifiers had been off in a about two months! I was glad to get it all going again. Carrying the transformer back to the other side of the school on the other hand was another matter. This was the small one, it only weighed 25kgs! Moral of the story... Get everything (well, almost everything) that connects to the mains tested every few years. Especially if it was made in the last century! I did have a vacuum cleaner catch fire.. Daniell

No further news about this fire yet, so we don't know what caused the fire. Might well be that they write "transformer" but actually refer to "power supply". I remember a case where a fire was caused by a defective laptop power supply. Owner let the supply plugged in all the time. Insurance company didn't pay because they said the device was not made for perpetual operation. In general it's a good idea to disconnect all consumers that are not needed and that don't have a primary switch (some computers have a primary switch at the back, some don't even have one). And maybe one day we'll get further information about the cause of the fire at Betzenhausen.
