Crispy, or extra crispy? [scared] [eek] [blink]
So yesterday evening I went down to the basement to fetch some water, I came by the distribution panel and thought I'd take a look - something I do every other week (loosely).
When I looked through the window of the housing to our 3, private, 50A main fuses Warren Zevon started to play & sing in my mind: "Send lawyers, guns and money, Dad get me out of this" ...
This is what I saw. (Obviously I checked for temperature & voltage first, took out the the side cover so I could look inside. Only then I took the pictures!) The fuse did not terminate the connection/ trip. That's why I/we didn't notice this.
To work on this I would have had to pull the 3 ("utility owned") 63A main fuses. I don't do this. So I decided to call an electrician in the morning. After a night with not much sleep, I had to call up about 6 electricians before I got one, at about 11 AM that was interested in fixing this/ taking a look. I spoke to the owner/master electrician, he said he had a journeyman not far from us on a site, and would call him up. Ten minutes later he called back to let me know the journeyman was on his way and would arrive within another ten minutes. That was awesome, because other electricians I had reached earlier in the morning told me about lead times of several weeks, even months. Some didn't even answer their phones/ had their offices not staffed.
So the journeyman arrived and did the same testing I did the night before and proceeded to remove the fuse and holder. (I didn't do this as when I checked it was cold and no voltage was present where it shouldn't have been. And I thought since everything runs as normal, if I unscrew and can't get it back in - there is a phase missing, and whatever is connected to it, wouldn't work anymore. By chance it's a fridge or freezer and that would be a problem.)
So that's when I really realized how lucky we were that this didn't cost us our house. Time to really thank the big guy, and the industry for coming up with plastics that smolder and melt, but do not necessarily burn without a flame present ...
This is the fuse (still working) and the smoldered holder.
After the housing was removed:
And everything renewed, up & running again.
Then it was time to go "full CSI" on the culprit. And yup, that's extra-crispy please.
Originally the electrician wanted to renew the whole cable, but came to the conclusion he couldn't pull that off without disconnecting any and everything and basically re-setup the whole breaker box where these 3 cables go into. So he was lucky that cable was long enough to be cut well beyond the damage, a new crimp, and good as new.
Since per Stig's ( [member=71478]FestitaMakool[/member] ) recommendation, I bought a new type (VDE) insulated pliers, I consider this my sacrifice to the god of insulated tools and the goddess of electricity ...
