Help with filling out EICR with economy 7

[JiMMySnoW]

Evening all,

I carried out an EICR on a property with economy 7.

I tested the main board like normal and only carried out the dead tests on the econemy 7 board. I have read the forum suggests about the live tests and taken notes for later tests with econemy 7. For now I am just going to put it as a Lim.

My question is in the box that asks how many sources do I put 2?

Not all economy 7 or 10 have a time clock.
They are fed directly from the meter.
Technically they are a separate installation.
There are two methods for testing:
One is to wait until the board is live.
The other is to take a feed from the normal board to the Off peak board.
Another method is not to conduct live tests at all.

Third method is the alternative Zs test using the 24hr L

Thank you.

I phoned the NICEIC. They said that I can do the follwing:

1) wait until it becomes live.
2 ) calculate the zs as per OSG section 10.3.6
3) phone the dno .

I said about linking over. They said they wouldn't recommend doing that for obvious safety reasons

Calculating the Zs is a waste of time unless you have all of the parallel paths exactly measured to factor into the equation.

Perform R1+R2 tests, calculate Zs's using measured Ze from main DB, note on cert you have done this, job done. Am I missing something here? Only reason to link would be if RCD/RCBOs present on e7 board.

Waste of time calculating, you might as well not bother at all.

To my mind, when completing the form for test results, only the results from tests performed should be recorded.
In this particular instance, (unless the normal live is linked to the off peak board), I would just perform and record R1+R2, polarity and IR.
