Not if you're referring to your latest post they're not. To get a shock the person has to be across both output pins of the transformer. Either pin can be dragged to earth without a shock. That's why it's called an isolating transformer.
I don't think 240V is that bad. I did drop a live light socket on a lead into a fish tank and put my hand in when I tried to catch it. At best it was a tingle and all the fish just swam about as normal. I don't think I will do it again but I was only about 10 at the time.
Of course statistically its insignificant and YMMV.
I've been reading this thread and I'm left wondering two things:
These isolating transformers seem to have been around for decades, whereas RCDs seem to be a more recent invention. Reading Graham's comments (above) is there an argument that bathrooms would be safer if the socket had no transformer and was wired direct to a 30mS RCD?
The other thing I wondered was if the OP decided to fir two isolating sockets, one for each device, or if you had a big bathroom with his and hers sinks and each had its own socket, would two sockets be just as dangerous as running two appliances from one socket?
I'm not an electrician, so I don't know but as the output from the two transformers would be in phase, if you held pole 1 on socket 1 and pole 2 on socket 2, would that have the same unpleasant effects as holding poles 1 and 2 on the same socket or am I barking up the wrong tree (if so, I did say IANAE)
