//! * Attach one green & yellow to the earth, one blue to neutral and two brown to the live. The second brown one can be thinner because it is only for voltage measurement.
//! * The earth, neutral and thin live wires should be long enough to protrude through the appropriate 4mm jack holes far enough to be able to strip and solder them to the jacks.
//! * The thick brown needs to be long enough to reach the socket.
//! 1. Attach the IEC inlet using two 12mm M3 countersunk cap screws, washers and nyloc nuts on the back.

//! 1. Put the thin brown wire the bottom right jack hole, add heatshrink sleeving and solder it to the brown jack socket.
//! 1. Shrink the heatshrink and screw in the three jack sockets.
//! 1. Solder a 13A green & yellow wire to the remaining green jack socket, long enough to reach the 13A socket. Add heashrink and fit it to the top right jack hole.
//! 1. Solder a 13A blue wire to the remaining blue jack socket, long enough to reach the 13A socket. Add heatshrink and fit to the bottom middle jack hole.
//! 1. Crimp appropriate ferrules to the three wires and connect them to the 13A socket.
//! 1. Screw the socket onto the top of the case using two 20mm M3 countersunk cap screws.
