rcd times at x1 and times x5

[james king]

this is confusing me.

now i know that the rcd times are ....

bsen 61008 and 9 should be less then 300ms
bs 4239 should be less than 200ms
rcd sokets at 200ms

but say i have tested a rcd at x1 180 degree = 35.2 and x5 at 180degree at = 12.6

if i remeber correctly is it

x1= max 50ms
x5 = max 40ms ?

x1 <300ms 200ms for older bs types
x5 <40ms

thank u acat.

what i do is put down the highest reading i get so eg.....

x1 0' = 26.6
x1 180' = 35.2

x5 0' = 7.6
x5 180' = 12.6

so i would use 35.2 and 12.6 correct?

correct use the highest readings.

yes you record the highest one time value if the cert does not have space for 1x and 5x. If it has room for both record both
