And also when measuring current, we can't just measure across a wire; we would have to cut it or splice it in half so that we don't blow the fuse to our meter. :)
100% BS fake. There is no component or trace in a multimeter that will be able to generate that degree of explosion when connected to any typical line voltage 120, 24, 208, 277 or 480volts. The trace will simply flash open like a fuse.
@Gizmologist09 They all have specially rated fuses inside anyway so yes I agree with you.
(As I'm told): Our maintainance guy tried to meter the 480 feed to the building with a Fluke 87. The slight problem was he metered the 13.2 side of the pole pig and POW. The meter blew up in his face. I guess 13.2 can overcome any fuse or board foils and cause a big explosion. I think handheld meters aren't rated against that high of voltage maybe a few KV and that's it.
@PFCSmith07 you mean don't test volts with resistance or continuity selected. AHAHAHAHAH! Not everyone can afford a fluke, there are lots of other good multimeters out there. Just watch eevblog.
I think this was done at Kinectrics in Canada where all the arc flash testing is done. Pretty amazing. They have a better video camera now. Might redo this one!
I just bought TWO multimeters for a basic class. How do I tell if the units are FUSED? SPERRY DM-210A AND CEN-TECH ITEM 90899. The cheap one from Harbor Freight for $4.00 says "fuse & diode protected circuit" ??? And what is done to cause that explosion ??
It is very common for someone to use a multimeter to measure 600V. This is a very common practice that electricians perform daily that could easily be prevented by using fuse leads. A simple user error like have your meter on the wrong setting or plugged in the wrong spot is all it takes. We have investigated many accidents like this.
Thankfully my meter is fused to 20 amps, and even fused to 2 amps on the lower current settings. That would indeed be a nasty accident waiting to happen otherwise.
Fused at 2A or 20A many of the meters have that small fuse just to protect the meter. Most of those fuses are not high interrupting capacity and can't interrupt the fault. I think our fused leads are rated at 100,000 interrupting. You could have the smallest or largest fuse, if it doesn't have the right KIA it won't clear the fault this will happen.
Oh yes; I had over looked that point, They are ceramic filled for high interrupting currents, but I don't know the figures and would only protect for the lower voltages and currents. Thanks for reminding me, I should know better. :)
am I right in saying this?

There may be a bang but not like that.

Dont test for resistance or continuity with volts selected. AHAHAHAHAH! Get a fluke!

@hannobisschoff1 good to know, I was testing for 10k VDC today on a turbine, that was assured to be cold. Very unsettling day lol

Ya we could not find anyone to hold the meter, a person could move a little but I think the explosion is so fast it would be hard to avoid.

is the person in the video some kind of robot? he doesn't move like he is locked up and any one else would have moved i'm sure...

600 delta or 600/347 is a popular in Ontario Canada. The same thing can happen at 480 other other voltages.

Pardon me for asking, but I don't deal with industrial electronics. What uses 600V +? I've heard of 480, but 600?
PaulyCracker 3 years ago
Here in Canada all our industrial power is 3 phase 600v which gives you 347v single phase
