I've bought a 2 pin connector with the intention of making up an

I realise that it is not keyed (ie there is nothing to make sure that

halves to try and ensure that live is always connected to live what
will happen if I get it wrong ? Will the RCD trip, the mower motor go
backwards, loud noises and lots of smoke etc???

No, the mower will just go as normal, it doesn't matter which way they are
connected.
