My OCPD (BS7671 Test Sheet)

[QuestionableSpark]

Hi,
Main LVAC Board, Directly Fed from a Transformer.

What do i put as an OCPD on my BS7671 Test sheet? Since I don't believe the Transformer has a BSEN number?
If it Does, Where would i find this?

Thanks Again!
(Learning and struggling with testing! More complicated filling the sheets in compared to the physicals tests!)

The transformer is not a protective device just put DNO, NV.

Hi,

Is this a privately owned installation (client owned the Tx)?

Transformers are not O/C protection devices.

The switch which is first in line from the transformer LV secondary side is your main incoming switch this is what should be recorded.

Presumably the main LVAC board has an OCPD incomer, that would be your supply protective device.
