IR is tested at 250V instead of 500V.

 

[SPECIAL LOCATION]

As spin says 250v

so as you know for future info its Table 61,

Page 158 of the big book is where you will want to reference to.

or table 10.1 on page 83 of On-Site-Guide.

Have you got, or can you borrow a copy of Guidance Note 3?

2.7.8 on pages 40 & 41 gives more detail about the requirements for insulation resistance testing of SELV circuits.
