I just finished a lighting wiring job yesterday in a kitchen: Two triple spot fittings for each half, each controlled on its own 2-way arrangement from both doors. The switch at one doorway is a 3-gang, the third being for a supplementary spot above a worktop. The switch at the other door is a 4-gang, the extra two switches there being for lights in a little utility area and a "mud room."
Obviously that little lot involved a fair amount of switch wiring, all with new brown/blue and brown/black/gray cable.

I have one word to say: Aaaaaarrrrggggghhhh!

O.K., I feel better now...... [Linked Image]
