  You might consider using an isolation transformer during testing.
That way you can also use other grounded test equipment - o'scope,
etc.  If the power needed is low and you do not have or can't find
an isolation transformer, two lower voltage transformers can be
wired back-to-back and used as a substitute.
	=>110v||24v=>24v||110v=>
Whichever way you choose, be careful.  Most folks are not use to working
on micros with deadly voltages present and needless to say, it can be
dangerous.

I have a project with LPC21xx, directly supplied from non-isolated 
mains. Is there a possibility to optically isolate JTAG use ULINK? For 
development purposes I can use isolation transformer, but I would like 
to isolate hot part of the circuit from my PC to avoid any fatal 
accidents and stil have JTAG debuging.
