From an "out of town" perspective,
Think about this.
Some years back I was involved in turning a Bank into a Chinese restaurant.
The building itself was solid concrete, with the walls measuring 3ft thick and the floor between the upper and lower levels measuring 2ft thick.
2 Months of solid work anyway.
Anyhow, the building owner changed her mind and wanted all the lighting controlled from downstairs, about 2 days before we were due to finish the job.
I seemed to remember seeing an old un-used fuse box on the upper floor next to the bathrooms.
That's what an Apprentice and I did for the next 12 hours, was pull wires into that box.
I ripped the innards out of the box and made up a 40 Way connector block.
I sealed it with a special screw that very few people have access to.
And put a voltage warning sign on the front, as there was 400V in that box.
I even bought the apprentice a beer that night, he really worked outside of his skin that day!.
