Should rewirable fuses be pensioned off?

[oracle]

The 3036 re-wireable fuse link was invented long, long, ago, but according to the standards list became a BS standard about 1957.

Tried and trusted in standard form, it has probably been the most abused electrical component, with wrong fuse wire, paper clips, hair clips, copper wire etc fitted.

Yet even the 18th edition includes tables for them. Let's take this poor old, badly abused fuse and put it into retirement. Like the ghost of Christmas past it's past its heydays.

I once did a board change after a rewirable CU had burnt out and couldnt get the client to see that the mcb and a fuse are serving the same purpose. "What do I do if the mcb wont reset?"......"Well that would indicate a fault was present and you'd probably need an electrician."
"So you've only fitted them so I have to call you back and cough up loadsa cash"?
" But the same applies if your fuse keeps blowing!"
"Ah, but I can mend a fuse....."
"But if it keeps blowing....."
"I'll keep mending it"
This continued until I gave up and left her content in her opinion that she'd been conned by the unscrupulous electrician.

I had that after fitting a plug in mcb in place of a fuse after correcting a fault. Called me three years down the line demanding I come and remove it as it trips and won't reset. Was called a robber after telling the old dear that any visit to fault find would be chargeable.

IT'S a non-brainer really , rewireable fuses are and always have been a nasty piece of kit , open to all sorts of abuse and for example will not blow or melt until probably around twice the design current is reached.My view is that these monstrosities should be totally outlawed, the sooner the better !

Deleted for fear of retribution.

Totally.

..... will not blow or melt until probably around twice the design current ....

Do you have any nice charts that show how MCBs fare any better !

rewireable fuses , fitted with the correct fuse wire, are inherently safe. you can't allow for farmer giles fitting a nail in the holder, same as you can't allow for plumber percy bypassing a MCB when he's fitted a 12kW shower on a 30A MCB.

Europe use bottle shaped D and E type cartridge for domestic fuse boards so you can fit a lower rated fuse in a higher rated holder but not the other way around

it's a pity that Europe ( the EU) did not consider that they could fit a low rated country into their federal superstate, but not this higher rated UK.Brexit...bring it on. dealor no deal, we are OUT. ( sorry to derail the thread, but the whole issue boils my blood).
