Hi Everyone

Quick intro, I have recently started house bashing due to twice being made redundant first as an auto spark and second more recently a server electrician installing power systems to servers and the likes.

Anyway, A recent call took me to someone bathroom with a ceiling fan fault. Did the usual diagnosis and found fan unit to be faulty. My question is, both the fan (240v) and the isolator are positioned that they are in zone 2. Looking at my trusted greenie it seems that this set up does not conform (if i have interpreted it correctly that is). My dilemma is do I replace fan anyway or report this as not conforming and price up accordingly to correct such.


In commercial/industrial land we always worked on the philosophy " if i don't make the existing installation any worse then go ahead (within reason of course) but, Domestic land is a whole new beast and usually is last man frees all.

any help guys and gals would be much appreciated.
 
Change the fan to a 12 volt fan, find the supply to the isolator at the bathroom light and divert it into the loft or to a cupboard if possible, fit a transformer and the isolator will be 12 volts just like the new fan :grin: Sunday morning tin hat on, let the fun begin haha
 
Surely the entire house needs rewiring if the fan doesn't conform:leaving::leaving::leaving:
 
you know it makes sense.

Steam is created by water vapour condensing. It does not require the water to reach 100c for steam to be produced. Steam is actually invisible water vapour condensing to form tiny water droplets as it spreads into cooler air.

I've had many showers and opened the door and steam has billowed out.

If it req. water to be at 100c then no one would need a fan in the bathroom.
 
sorry, mate, you're way out. starting at the bottom, you have ice, water, water vapour, and then steam. the stuff in your bathroom is water vapour. steam is invisible, and it's bloody hot.

Steam is created by water vapour condensing. Steam is in actual fact invisible water droplets. A shower at 40c can create steam and set smoke alarms off.
 
and when water vapour condenses, it becomes ..... water. and it's not just internet info. i have A level physics and as part of HND did physics theory almost to degree level. steam is invisible as it's a gas, not vapour.
 
I'm pretty sure condensed water vapour is most commonly known as 'water' - 'steam' is the gaseous form of water which is produced when water is heated to 100 degrees Celsius and what was used to power trains.
I don't see how a switch in a bathroom is going to be affected any differently to one in a kitchen; the idea of using a pull switch in the bathroom or switch outside the bathroom was to reduce the risk from operating it with wet hands, not to prevent water ingress. Generally speaking a fan isolator is intended for maintenance, which isn't usually carried out by someone who has just stepped out of the shower.
