I'm moving a CU about 5m on a rewire and as the tails will just be surface mounted 6181Y I'm planning on sticking one of these in - Wylex 100 Amp SP&N Switchfuses - has anyone used one before?
They just seem pretty cheap...

Yes mate, I use them all time for this type of job. They have been the de-facto standard in the industry for decades.

Slightly hijacking this thread as its been dormant for three days .............

OK the Reg is >3m tails must be protected by a switch fuse. But if there is the mains incomer cut-out fuse and a double pole isolator is fitted straight after the meter ..... why do you need another fuse and another isolator? This could be one of my many senile dementia moments .........

it's to protect the DNO fuse from a fault on the tails. the 3m rule is an arbitrary length.

I have used one of these quite recently for the first time. Very easy to work with even when terminating 25mm tails. I did however opt to order the 60A fuse so the spare 80 sits in my van :thumbsup

It's now looking like it may have to be run in SWA, is there an earth terminal inside the enclosure?
