presume thats in the 18th edition of the big expensive book of multiple amendments as i remember this coming up on the 17th course which led to a discussion about the difference between a fuse and an mcb.

Yes, let me just rush out and get spark to rewire my home for £4000 adding a whole new set of 4 plug rings and dozen new plug sockets tracked into the walls.
I checked for fires, there are some, but either because people are dumb enough to run 16 Amp heater off a 10 Amp plug or because they did dodgy hacks to them, like this guy:

Emmm... running wall heaters on them and hacking an inappropriate diode into the main line. It's also an older model with non reinforced tracks. Darwin award in my view. You just can't fix stupid.
Mine are rated to 10A and I do not intend to run anything close to half of that on them. I'm in the UK so all my plugs are fused so if the device connected to the switch shorts the plug fuse will blow, there will of course also be a fuse in the 4 way power bar or it's plug. I can go as far as replacing the fuse in the plug with a 5A fuse. The switch itself has a fuse for it's own power supply and it looked to be up to standard when I took it apart.
I have done a bit of due diligence and it does look like the CE marking on the device is valid and the company is prepared to send the test reports and certificates to you on request. This would mean that as long as they are not modified my house insurance would still be valid.

Does these things catch fire alot ?, it wont be more risky then charging a LIPO accu, right ?
bd139:
They don’t catch fire that often. They’re as dangerous as a soldering iron really. Don’t leave it unattended and have a suitable extinguisher available and the risk is low.
The biggest risk was the Anet A8 which has an entirely plastic frame which was flammable and in all cases where it burned people’s houses done it was unattended from what I could see. The Ender 3 has aluminium extrusion parts so fire spread risk is mostly the PLA and electrical failure.
Jan Audio:
So where do you all place these things ?
What is your safety plan ?
What is your setup.
Mmmm, do not leave unattended, so in my shed no.
On the balconny, yes.
In the kitchen, yes.
I,m gonna read the manual first before ordering.
Look what the manual says : Never use the device to make any electrical appliance.
They are meaning 220volt i think.
