Is a stripboard strip designed for 240V?
This is the stuff I presume you mean: -



In the UK it used to be called veroboard and here is a specification issued by the manufacturer: -



Note that the Ministry of defence recommended maximum voltage is 500 volts. 240V AC peaks at about 340 volts but I'd be concerned about using adjacent tracks for mains voltage.

Details taken from here.

I would urge you to contact the supplier of your strip board to see what they say. Also, given the sort of working environments that strip/vero board is used and the potential for contamination landing between tracks I would be very cautious about using it at 240 volts.
