[Amps] what is a 4 wire 240VAC service

Perhaps the switch location has a dual role: up/on = occupied, down/off =  
unoccupied?

That must explain the bathroom light  switches in my house here in New 
Hampshire, they all are on the outside  wall instead of the inside.  Maybe we 
had a UK trained electrician!

It is a lot safer. They use isolation transformers and 115V on  building 
sites in the UK. 

UK code will not allow light switches in  a bathroom. It either has to be a 
string pull switch in the bathroom or a  wall switch on the wall outside 
the 
bathroom. There are no 240V power  sockets allowed in the bathroom apart 
from 
transformer isolated razor  outlets. 

Lots of people in the UK die using 240V electric mowers and  cutters 
outside. 
It isn't 120 0 120 like here. It is 240Vrms relative to  the Neutral/Ground 
potential. That is 660V pk to pk relative to ground.  You take a shock and 
it 
really hurts if it doesn't kill you.
