Are you all organised and have a supply of the new certificates to hand?
What do you actually think of them?

| 10 mA |
| Conduct both 1x and 5x tests Record the 5x result. Verifies both additional protection to 643.7 and ADS to 643.7.1 b) for 0.2 s and 1 s disconnection. I would be able to demonstrate compliance with Regulation 411.3.2.4 and 411.3.2.1. |
| 30 mA |
| Conduct both 1x and 5x tests. Requires loop impedance less than 1364 Ω if you take into account full volt drop Record the 5x result. Verifies both additional protection to 643.7 and ADS to 643.7.1 b) for 0.2 s and 1 s disconnection. I would be able to demonstrate compliance with Regulation 411.3.2.4 and 411.3.2.1. Whilst the full Zs of 1667 Ω presented in Table 41.5 wouldn't provide sufficient current for a 5x test with lower voltages, earth electrode resistance should be limited to 200 Ω so no issues anticipated |
| 100 mA |
| Conduct both 1x and 5x tests. requires loop impedance less than 409 Ω if you take into account full volt drop Record the 5x result. Verifies ADS to 643.7.1 b) for 0.2 s and 1 s disconnection. I would be able to demonstrate compliance with Regulation 411.3.2.4 and 411.3.2.1. Whilst the full Zs of 500 Ω presented in Table 41.5 wouldn't provide sufficient current for a 5x test with lower voltages, earth electrode resistance should be limited to 200 Ω so no issues anticipated If you are asserting it's unsafe to test the RCD at 5x in domestic, then do and record the 1x, but now you only have verified disconnection at 1 s and compliance with 411.3.2.4, and therefore in domestic this RCD can only provide ADS for distribution circuits, and final circuits not covered by 411.3.2.2. |
| 300 mA |
| Not practicable (or perhaps safe) to test at 5x, so we are limited here to testing at 1x. Record the 1x result. Verifies ADS to 643.7.1 b) for 1 s disconnection.

| 100 mA Type S |
| Conduct both 1x and 5x tests. requires loop impedance less than 409 Ω if you take into account full volt drop Record the 5x result. Verifies ADS to 643.7.1 b) for 0.2 s and 1 s disconnection.
