Merlin Gerin now comes under the branding of "Schneider Electric"
Is it a main switch or an RCCB (an RCCB has a test button on it)?
Maybe just a coincidence with MG codes, CGD (Control Gear Direct) is another manufacturer but their quality is nowhere near the same as MG.
that's a very cheap brand, and not Merlin Gerin
tell us more about the burning
do any of your friends or neighbours know a good electrician?
are you far from the nearest fire station?
I have to agree with JohnD, CGD are very budget. If it is a Merlin Gerin consumer unit then it is a good idea to fit Merlin Gerin products as they are fully type tested, but unfortunately being a good brand bumps up the price a bit!
