Hi Topaz,
I hope your arm is better and no lasting damage is done. I have been shocked many times - I grew up on a farm and had most of them from electric fence chargers and spark plug discharges - those spark plugs were the worst! Shocks from 240V AC are really at 120V since the neutral and ground are at 0 volts and the 240 volt is referenced to the other line which is 180 degrees out of phase with the other line. Or think of one leg of 240 volts is at +120 while the other leg is at -120 . Now if you grab one wire of the 240 in each hand then you will have 240 across your arms and 120 across your legs to earth. The sensation of 120 V is a combination of burning (hot) and muscle contraction/stress. In my case I could not turn loose until the fellow who plugged in the ungrounded tool (I had complained about getting minor shocks and unplugged it) I was working on unplugged me and while I remained conscious, I could not move. There was a big safety meeting the next day on that construction site!
Another electrical shock you may be experiencing could come from a pinched nerve like your funny bone type of response. I mention this because I have such a nerve in my foot and sometimes pressure on it creates a similar burning and tingling sensation - but if you are wearing a rubber glove and don't get this sensation, it's probably not the problem.
I would recommend you to ask the electrician to check the performance of the GFI or ground fault interrupt protection. As Ingineer mentions, this is the protection method and does not depend on a working ground.
Another question is the conductivity of the socket on the LEAF that the latch goes into. I thought this socket was an insulator material and the latch is on the outside of the socket shell.
Finally, I hope your electrical systems check out okay and this can be explained/tested by your electrician and put your mind and arm at ease.
