5a to 6a

[ashley124]

can i change a 5a fuse to a 6a for my lighting circuit?

Many thanks

Yes

I take it you mean a 5A fuse to a 6A MCB? Providing the efli is acceptable it can be changed. If you don't know the efli value then I urge you to get a pro in.

I think he prefered the first answer.

It will be interesting to see how he reacts to advice he doesn't like....

Listen, I bought this effin house with all my own (well, maybe Daddy's) money, and I'll do as I effin well please. I don't know why I bothered coming on here. You're all useless ****ss, and if you dare to cross me I'll break your bleedin' arms!

if the EFLI of a 1.0mm lighting circuit protected by a B6 (or even a C6 or B10) doesn't meet on the kind of cable lengths you'd get in a normal house the installation or it's supply is seriously f*cked up.

21m for 1mm² on a B10.

So one circuit on a 2-storey 3-bed house, cable ambles and zigzags around in the ground floor ceiling, then does the same in the loft...

Not beyond possibility that it might go over that....

 

[plugwash]

i'm sure i did the calculations and came up with a figure much higher than that for the cable length.

That 21m is based on volt drop at a full load of 10A. The EFLI would be well within the limit, but the circuit lengths in Table 7.1, OSG are more often than not based on volt-drop rather than EFLI.

 

[ban-all-sheds]

Yeah - you're right - I was in a hurry, and didn't follow it through properly

If EFLI is the limit, the OSG flags that, doesn't it (e.g 9m if you want to put your lights on a D10).


Anyway - Ashley has gone very quiet - wonder what he's up to.....

Perhaps he's learned about electrickery the hard way?

I speaks ill of me but my sense of schadenfreude secretly hopes so...

 

[ban-all-sheds]

Not too hard, I hope...

I'm a big fan of The Darwin Awards... nuff said.

Based on his previous posts I bet he's tucked up in bed grooming a fresh 100amp BS-88 for his in-cummer
