    operating a fan from a thermostat and a humdistat at once

    If you want the fan to run when the thermostat says the room is too hot and also when the humidistat says there's moisture in the air then yes all you do is wire them in parallel. This means that when the thermostat says the room is not hot and the humidistat says the room is not humid then...

    Adding a permanent socket which plugs into another socket

    I've been told by an NICEEIC registered guy that because you are taking an earth from one equipotential zone into another that this connection must be permanent and not plug/socket...that was his answer to my question about what's to stop people plugging their shed in with an extension lead :D...

    Testing & certificates

    Having been a tenant many times I've never had an electrical safety certificate, only gas. I don't think you need to get one for the electrical installation or any appliances that you may have in the property.

    Broken energy saving bulb

    Indeed, for several years I have always taken a flight over to china to return each low energy bulb that I have had fail to the manufacturer. Somehow I think that these bulbs are having a greater enviromental impact on the planet than the ones I used to just throw in the bin :wink:

    60A main fuse 100A breaker?

    70A, have you applied any diversity factors? If it is maxed out then explain to the customer that you can't continue and will charge them for the work done so far and leave the installation in a safe condition.

    Stupid Question

    If there is a poor connection from the main neutral to the neutral bar then yes you will get a PD on the bar and neutrals. I once heard of an apprentice telling a works electrician that he just had a shock off of the neutral bar in a fuseboard, not believing him the electrician tried it for...

    New light fitting problem

    The security light is switched? Then check you have power at the switch. Was the security light working before you changed the fitting?, In my experience the bulbs in these things blow quite regularly especially if it is a cheapy.
