I'm thinking of installing a Wylex 2 pole RCD 100 Amp 100mA
in a box like on the TLC page linked below.

Just after the main incoming electricity company fuses,
meter and isolator switch,
but before all the henley blocks, consumer units,
solar panel connections, old fuse boxes etc

The supply is TT, I have 2 earth spikes outside the door.

Any advice for or against?
