Max Zs please...

[flyingsparks]

Hi guys, can someone let me know what the max Zs is please for a 5A BS3036 (the actual time to put on my form please not the 80% value)under the new regs as I dont have my regs book here! Also max disconnection time (it's a lighting circuit) and its on TN-S.

Thanks...

Final circuits below 32A are all 0.4s.
For a 5A BS3036 the Zs max is 9.58ohms for a 0.4s disconnection time.

3036 zs 9.58 ohms for 5 amp circuit 2.5 ohms for 15 amp circuit 1.77 ohms for 20 amp circuit 1.09 ohms for a 30 amp circuit

Are we talking 17th? ALL final circuits <32amp are 0.4?

Alteration or addition ? Is the circuit protected by an RCD?

TN system @230v AC sorry
Should be not exceeding 32A too

Thanks guys!

No RCD as then it would have been 1667 ohms, it doesnt matter if it is an alteration or addition, does it?

If you have installed new cables, then yes, most probably.
