UL considers the breaker tripping during transformer tests a FAIL ... Troll be gone
The following users thanked this post: Electro Detective
It was literally seconds. If I hadn't pulled the plug and tossed the unit in a box to trap the smoke, the building ...
It was mentioned in the video, and the topic. When people believe something hard enough, it starts to become reality in their head. But oh no ... I'm a troll and a corporate schill
People are starting to feel very threatened and take this VERY personally
@ timelessbeing, there's no feeling threatened or personal vibe here mate
(puts on Kevlar rig and face shield, downloading anti-malware update...) Back to the topic...
Regarding breakers:
DJ states he has a 16 amp RCBO breaker (single or dual space combined RCD/GFCI and MCB)
e.g. If a 140 amp transformer welder pulling constant and intermittent 15 to 35 amps current at 240v
at near and full short circuit conditions on the transformer secondary (during actual non stop arc welding with 3.2 or 4mm electrodes)
it will do it tough to pop the 16 amp breaker but may/will eventually...
this is assuming the welder and leads are in good shape with direct plug in connection to a standard GPO wall socket
(i.e. no amateurish backyarder flimsy 10 amp extension cord malarky)
So what chance has a sizzling lil Weller trannie got to pop DJs breaker ? > PowerBall win chances ?
At best if it's plugged in to a 4 or 6 way power strip board with a thermal breaker/Reset thingie, the ones with the small black or red switch usually near the cord entry,
it may heat up around the 8 to 12 amp range (depending on the breaker design/curve) and trip the power board.
i.e. you can forget about MCBs and RCDs popping...unless the Weller is pulling over 32 to 44 amps for over one minute
and or the IEC cord catches fire
and or IEC socket melts, falls inside/outside and shorts/welds itself. Then perhaps the MCB and or RCD 'may' trip
...assuming those devices have been tested and their switches exercised at least a few times yearly
I'm sorta convinced if the Weller was allowed to keep going, and the adjacent insulation stripped windings merged/spot welded themselves together, instead of breaking,
then DJ would have had himself a nice block of red hot glowing metal, an unhappy ESD mat, barbequed bench,
and lots and lots of Majique Smoke...
btw: do I still need to donate the $50 now, after cobbling up this long winded electrical blab ?
