Hi
This is my first post on forum, so be gentle with me !!!!!
I'm in the process of converting our Leprechaun for 240 volts. I intend to put just one UK double socket for the odd bit of kit that is 240 only and keep the present 110 sockets for modern 110-240 appliances.
Instead of using a yellow auto transformer(which only has one winding and the potential in fault conditions to apply 240 volts to the output) I have a 3.5kva isolating transformer(primary 240 secondary 110). This will feed the existing breaker box along with 110 volt generator to power roof A/C, fridge, battery charging and 110 domestic sockets (microwave has been changed to a new UK one).
My problem is this transformer has the centre tap of the 110 secondary connected to earth so output legs are both at 55 volts above earth, and I not wanting to damage the A/C, or anything else, don't know whether to leave it like this or disconnect this earth ????
I have looked around the forum, but cannot find a similar query.
Any advice would be appreciated
KIND REGARDS
