I do know how to solder. :-) However, if I try to certify the electrical installation, I would have to redo them, meaning rewire the second floor (first floor in EU) entirely. And unless I certify, the electricity company refuses to increase the Amps, which is why my house is limited to 10A. Instead, I'll move house. -- Cheers, Carlos.
