Shower Location Question

[slightly/clueless]

Hi everybody,

Will anybody be able to help me out with this question? Regarding locations containing a bath or shower, additional protection by RCDs to regulation 415.1.1 of the 17th edition regs states. The use of RCD with a current rating not exceeding 30 mA and an operating time not exceeding 40ms at residual current of 5 1Δn.

Is this telling me that the reading on my meter when testing the RCD covering the circuit is less than 40ms on the x5 setting?

Thanks in advance for any advice on the matter.

What were the rcd test results .... And is this a new install?

 

[telectrix]

for most applications, a 30mA RCD must trip in <40mSec. @ 5 x Δn. bathrom is no exceptoin.

1Δ within 300ms on both 0° and 180° with the highest recorded.
5Δ within 40ms on both 0° and 180° with the highest recorded.

1Δ within 300ms on both 0° and 180° with the highest recorded.
5Δ within 40ms on both 0° and 180° with the highest recorded.

That's not true for all RCDs

That's not true for all RCDs

Referring to time delayed or old ones?

and then there's RCDs on TT systems.

Both

And then there are GFCIs wonder how or if they ever test them in septic land? they just seem to bung em in willy nilly.

Seeing's though we're all getting a bit picky - its Xmas, peace on earth, good will to all men & all that ; the OP's title is referenced by reg 701.411.3.3. Which itself refers to reg 415.1.1. using them thereof. The aforementioned reg, refers to low voltage circuits. Just getting in practise for me 18th exam, book reading skills.
