how to cure a blowing fuse

[Guest111]

Some latvian contractors had complained about a welder blowing a fuse on an extension lead repeatedly,Finally they announced they didn't need the electrician calling out as they had resolved the issue,yes that is a piece of an M6 bolt!

Overkill, M5 would have done..

 

[Richard Burns]

Cowboys, nails have much lower contact resistance than bolts!!!

 

[Badged01]

Smart guys! They realised the wire was covered by the C/B so they didnt need any secondary fusing .......

M5 would have been loose in the fuse holder and could have led to arks n sparks! Lol

 

[Guest111]

The laugh was the lead was a 50 foot length of 1mm flex,should have seen the overheating on it.

did they also wire the plug top with boxing gloves on?

 

[CockneyReject]

God they could of atleast jammed an m8 in there and done a proper job

not just the euro trash that do this, plenty of fencing contractors and farmers are experts in this line of work

You're all cowboys! I always use a piece of 1/4" brass bar parted off to a 1" length. :smug:

The cable sheath is in the clamp which is not easy with that sized flex so I doubt they wired it.

 

[gnuuser]

yeah they let the magic smoke out
you know when they do this type of **** they deserve the darwin awards:90:

most welder manufacturers specifically state that extension cords or leads must not be used.

 

[Knobhead]

Could you tell me the protection built in to US plugs and sockets?

The entire US electrical industry deserve a Darwin award.

 

[gnuuser]

actually some appliances are coming out with fused plugs and gfci.
dont get me wrong tony I agree with you and i wish we had fused type plugs like you guys use
but I have to work with what we have.
this is also the reason my home is wired for low voltage control (only outlets are at 120 volts)
all lighting and switching is at 24 volt.
also solar cells charge the battery banks for emergency lighting
the side benifit is a lot lower cost in wire

my statement about earning a darwin award is for those who would replace a fuse with a solid bar.
fuses are made to burn out if the current draw is exceeded this is a sacrificial safety element.
purposely bypassing a safety device be it a fuse or safety switch is just asking for problems.

Fault finding I replaced a 450A fuse with a solid link, so the back up was a 1200A ACB. After many abortive tests I’d run out of ideas. Found the fault, a tree falling over on fire gave the game away. Its roots had broken an UG joint.

I don’t recommend this normally but needs must at times.
I’ve done it a few times on 11KV (upped the protection relays first) to give a good short that could be traced. Wandering around fields in the middle of winter isn’t my idea of fun.

PS I've never work on domestic.

Do you leave that to the professionals Tony?? lol

You come in to my world. I'd leave you (for) dead!

In fourty years I've done five domestic installs. I had my arm twisted for them (bloody family + wife). I stuck with what I was comfortable with.

Best five jobs of your life?????? I Doubt it, and anyway.....where you part P registered?? If not, then your not qualified!!!!...........(i'm being extra cheeky to my elders now)!

part p is a new thing and i bet most of those installs were pre 16th

You've got a thanks for making me laugh.

Betters, no. Yes we're electricians but in different fields.
I haven't a bloody clue about domestic. But I'll ask do you know the M&Q or Foundries acts?

Horses for courses springs to mind.

My idea of running a cable wouldn’t involve chasing a wall. I’d just demolish it, run the cables through and the brickies would rebuild the wall afterwards.

You think I’m joking, I walked in the plant managers office and told him two 240mm3½c SWA’s were coming straight though his office. It was cheaper to relocate him than divert the cable.

OK I’m an animal, but its how my life in heavy engineering made me. I couldn’t do you’re job if my life depended on it.
