Can you replace just the RCD, instead of whole consumer unit?

Former Community Member over 3 years ago

My apartment failed it's EICR due to the electrician not being able to trip the RCD in the required time. I am told that the RCD cannot be replaced and a new metal consumer unit must be installed at a quote of £1180. The apartment was built in 2003 and seems overly wasteful to ditch the whole unit, however I am not an electrician so would welcome some guidance please before I commit to this remedial action.

This is the RCD currently fitted:
5760S | MK 63 A RCD Switch, Trip Sensitivity 30mA | RS Components (rs-online.com)

It appears it worked within spec for above 30mA, but failed for below, if that helps with whether the whole consumer unit must be replaced. See report.

The RCD is separate to the main switch, I now have photographs. I was mistaken in the RCD type, it is infact an MK Sentry 5760s

As far as I can see, the product has been discontinued, but there do seem to be some around.

When looking for replacements, would it matter if I found one from the same MK series with a higher amperage - 80A or 100A?
