Re: Transformer safety?
People were more wary of that fangled "Lectrickery" stuff then. It bit if you got too close, just like the then common open fire did. Most accidents aren't fatal though, and there was more of a "won't do that again" attitude than today's litigious and instantly broadcast one. It's inconceivable that there were less accidents overall though. The risk to us is that the old standards and attitudes, that we accept, are now judged by modern attitudes. You can't uninvent things.

Re: Transformer safety?
Just to show how times have changed, I have a manual for a 1950s amateur radio transmitter made by a British company which states -"Shocks: If shocks are felt on transmitter cabinet (no earth lead on rig) reverse mains plug in mains to cure this trouble".
This is a device that used over 1000V DC on the power amplifier anode! Cheers Roger Last edited by G3VKM_Roger; 30th Sep 2018 at 6:35 am. Reason: Quote changed |

Re: Transformer safety?
I realise the thread has drifted away from 'transformer safety' to general electrical safety but here is a picture of the electric fire I declined to fit a new mains lead to.
There is no switch and the mains lead goes straight to the element. There is minimal guarding over the bare element which is easily accessible with a finger. It would be perfectly feasible for it to be plugged in to a single pole mains socket with live and neutral reversed. The heater would be off but the element would still be live! The ceramic casing which contains the spirals is also cracked in half. So my own view was I would not be happy for 'normal' non electrically aware people to be using it. Cheers Nick |
