Re: Contract clauses

Got something very similar in my UK contract. Is the traditional basis of that clause not that you should get a bonus if you put in the extra work, though depending on the size of the bonus it is easily wiped out by working an hour extra per day?

Re: I've often wondered about the security of powerline devices.

The most effective thing to do is to insert an isolating transformer between your installation and the public grid. Another method is to wrap the incomer around a metal toroid which will block the higher frequency components.

Non-obviously it is possible to couple from one set of cables to another, so your neighbour could put a transmitter on their side of the wall and turn the power up...
