Releasing company fuse from mounting board and cooker cable size?

[Michael Chare]

Would they jump at all? The down side is that I would need to keep the power on to operate the tool and I would be very close to the cables to the meter.

[ARW]

No one will care.

I gifted my green Bosch to my elder daughter for decorating Pumpkins:-)

Battery multi-tools are available ...

Maybe a photo to show what it is you're thinking of doing?

[Michael Chare]

Thank you.

For my 50th. birthday an ex-gf gave me a green Bosch mains hammer drill (percussion nowadays) - of course, I haven't really used that since buying a combi about 7 years ago. With it, if claimed, was a 7.2V drill-driver. A bit feeble but v. useful in conjunction with 'proper' drills. It packed up this year, when the battery would no longer hold a charge, at the ripe old age of 19. Not bad for a small NiCad battery.

Just be careful you don't cut through the ?£"&*NO CARRIER

I had a bunch of early 80s nicads still good in the noughties. Well, except their capacity which was as poor as it had always been. 450mAh AAs IIRC.

Some of the cables will be live anyway - and unfused.

Be very afraid. It's supposed to deliver 25kW, so I hate to think what the fault power would be.

6000A 240v = 1.5MW. Hmm :)

1000+ amps typically (mine measures 1060A, if you have a substation next door, it could be very much higher).

[Bob Eager]

I wouldn't touch this with a very long, heavily insulated, VDE bargepole.

[dennis]

I think you are being optimistic, the main breaker in the substation is likely to be a few hundred amps and the fault current could easily get above 6000A. The first thing to blow would be the screwdriver/screw at explosive force.

[John Rumm]

PSSC over 6kA in a domestic situation is fairly rare unless you live almost on top of the sub station. Note also that many MCBs have a maximum breaking capacity of only 6kA. So if you really do have a supply impedance of under 0.03 ohms you have other things to worry about!

[tabbypurr]

If the MCB can't hack it the main cutout fuse will. But of course it's fusing energy is many times higher. Some MCBs are only 1kA.

[John Rumm]

Yup, that is the theory. Not good for discrimination or serviceability though! ;-)

Some of the very early "plug in" MCBs for old wylex fuse boards perhaps. Pretty much anything you buy now will likely be 3kA or better.
