Dangerous fuseholder wiring in variac
<< < (4/4)
Greg Robinson:
Another concern, I don't see a fuse on the output?!?
Thanks to transformer action, at low voltage output the input current to an autotransformer is low, but the output current can be the input/output ratio greater. Without a fused output, the brush and winding can burn out...

That's basically how most of similar fuse holders are made. Swapping wires won't help much since it still will be connected through transformer anyway. You may argue that Australian mains plugs are polarized but I would not count on that.

This.
At least, the way it is now, connection to live can be broken by turning off the switch (if you don't unplug it and not even bother to turn it off, you might be eligible for a Darwin Award).

That's how mine is. The fuse holder is wired in "backwards" (live end out) but to touch a live part someone would have to unscrew the fuse with the unit plugged in and turned on. I also noticed that all of the mains wiring was soldered  :-- Add to that the perils mentioned by the guy that tore one down and I'm going to have to look at this thing closer.

Sociopaths continue to build these mains-powered fire-starters because people like me continue to buy them. Maybe it's time for me to look in the mirror.

EDIT:

When I bought my current nest I checked all of the outlets and found that 3 (of the many outlets) had a reversed line and neutral.

Why not just return it and the same for the original poster?

These cunts shouldn't be allowed to sell defective products like these!
