How safe is a wooden cabinet?

You can get a tingle on microamps, way below RCD trip current. I get a slight tingle if I touch my earthed beside light when the electric blanket is on. Just from the capacitance between me and the blnaket element. If we take the capacitance as 10n, which seems high, that would be a 350uA current through me. This assumes an average voltage over the blanket of half mains.

I must take a DMM to bed with me one day. Then Ruth will be certain that I'm a complete nutcase
