Pre 2nd Fix Tests

[davegreen]

What pre- second fix tests should be done on a fire loop? If any

Fire loop check.......

I try and start at the panel end and check the loop as I fit devices.

Start by linking all the devices through and doing a continuity test. (don`t megga with any devices on LOL)

Panel should soak test I usually have that on the wall powered up with no loops connected .

Then start adding the loops one at a time.

When your happy that the loops are clear add devices

So connect all the cores through back to the panel, when it sees no fault start 2nd fixing? Is it essential to record contiunuity/ resistance readinds on the loop?

insulation tests

earth loop impedance tests

voltage drop

loop resistance test to see if correct amount of cable has been used.

continuity

autolearn

etc etc

test all looop isolators

test internal loop isolators

open circuit loop in and full load test

open circuit loop out and full load test

test all loop devices.

slightly more than "if any"

If you want to comply with BS5839 it is essential to record the following readings for all loops:

1. Insulation resistance L-N, L-E, N-E

2. Loop Continuity - L-L, N-N, E-E

However this is easier said than done when you attend site to commission and the electrical contractor has already fitted all the devices!!

[james.wilson]

He should provide the reading along with his install cert....

[g4vjc]

...if only!!

it's up to the installing electrical contractor to do all the insulation tests and record them...in theory
