why is the use of bs3036 not permited

[paulthemagpie]

hello peeps,

got a quick question i would be most greatful to get an answer to:

Why do the requirements of the 7671 for PFC may not permit the use of a BS3036, semi enclosed device as means of covercurrent protection on a home re-wire

regard magy

hello peeps, so the fact the question was specifically to do with PFC does this change the answers above??

thanks you

IQ has the answer for you, they may not have a sufficient breaking capacity for the PFC.

so im i right in guessing this question is asking why we wouldnt choose bs3036 over newer RCDs?

and basically it because it doesnt have the right min disconnection times

MCBs, not RCDs! it's not just the disconnection time, it's also the low kA rating. MCBs are rated far higher in terms of breaking capacity.

oh i see, so only possible to be used in small installation!

why would you even want to use 3036 fuses on a rewire, anyway. that's like using a WWI biplane to combat MIG 29s.
