can someone tell me the order of tests before making curcuits live after a rewire and why thanks
ORDER OF TESTS
- Thread starter tashie
- Start date
continuity, Insulation resistance then polarity
Its all listed in
BS7671
On Site Guide
Guidance Note 3
and
Just about any elementary book for electricians

thanks guys
Shouldnt earthing be on the end of that.?
Back in the days 14th regs
It was PEIC

Full list of items.
BEFORE CONNECTION OF THE SUPPLY
1 Continuity of protective conductors
2 Main and supplementary bonding continuity
3 Continuity of ring final circuit conductors
4 Insulation resistance
5 Site applied insulation
6 Protection by separation
7 Protection by barriers and enclosures
8 Insulation of non-conducting floors and walls
9 Polarity
10 Earth electrode resistance if an earth electrode resistance tester is used
WITH THE SUPPLY CONNECTED
11 Earth electrode resistance if an earth-fault loop tester or the ammeter and voltmeter method are used
12 Confirm correct polarity
13 Earth-fault loop impedance
14 Correct operation of residual current devices
15 Correct operation of switches and isolators
Some of these (5 to 8 eg) do not apply to most domestic situations.

But if you have an earth electrode resistance tester
You do that BEFORE the supply is connected
Thats in the on site guide
10.2.1 (v)
OR

OR
Would you not do 12 before 11
Well done anyway you had the earth electrode Number 10 spot on
