Changing 16A MCB to 10A

[LeeUK]

Could changing a 16A MCB to a 10A be safer to prevent over loading or dangerous if over loaded?

We have just had a cable melt at MCB and am thinking it might have been over loaded (holiday let).
Im thinking for safety, changing to a 10A to prevent this happening again.

To add - the MCB is dual pin N L (France) so not a single cable melt, it could have been poor wiring/arcing.

When you say a cable melted, what exactly do you mean? All three wires or just one?

We have just had a cable melt at MCB

If you mean one wire melted at the MCB terminal then it was likely due to a loose connection.

The MCB rating is dependent on the cable it supplies rating - what size is the cable? Over heating at a terminal, is most often due to poor termination, causing a point of high resistance, generating heat.

The issue was on the input not the cables out to socket.
The inputs were cable linked rather than a busbar so have replaced mcbs and used busbar
Probably a poor connection, it does look a bit of a mess, wires all over the place!
Hopefully tidied up now.

And the CONSUEL were happy when they did their inspection?
