there was probably some charged capacitor someplace. Just like esd, you probably gave it another potential and it discharged across you.
Are you talking about a fuse for your house? or just a fuse in a some ckt.

Ah a capacitive charge somewhere on the circuit would explain it if you didn't get a second belt.
It is unlikley, as most domestic circuits handle inductive loads, to such an extent that large factories with many a large electric motor, and tube lights install a capacitor bank to correct the power factor angle. Ideally 0, but 0,8 is acceptable.
Domestically, though I did re-wire someones house extension, as he had connected both ends of a ring-main to diffent fuses/breakers.
It should be a simple loop back to where is started, so one breaker wipes out the whole ring.
So it makes me ponder that the circuit that you got a belt from must have a connection with the wrong other supply.
I would meter the consumer unit to check that all rings arrive at the same breaker.
Mind your fingers !

The neutral in a panel by NEC code is not fused however the neutral in a panel can be shared by another circuit. If you we unlucky enough to get to that point where your resistance was lower than the ground potential and you were touching the shared neutral ,which by the way is a current carrying conductor,you might get some or all of the EMF available...There is no residual current in a cable once power is removed it is dead...From the E....

Are these house fuses?
Yes, you can get a shock because the supposed neutual is not always a grounded -- it 'floats'. The person who did the original wiring of your house tried to balance the load from a 220 circuit into two 110 circuits. This cause a residual voltage on the neutral wire which can give you a shock.

Any capacitors in the circuit would discharge if you touch both cables at the same time L+N, you can get induced voltage in cables (LV) but it is usually around 60vac, and has little or no current, not enough to give you a shock. On HV cables they can charge up with out bieing connected if the are in parrallel with other HV cables, but if you touched that it would blow your hand off...

It is not in the cable it is in the appliance that you removed the cable from. Will only be built up static from a motor or capacitor in the appliance. Indicates that you have a poor path to ground in the mains circuit.

Is there a possibility that there is another source?It happened to an aquaintance of mine in a factory, he had the fuses in his toolbag and nearly fried because there was another supply that wasn`t even on the circuit diagrams.

NO
something else is wrong. Check the back of the fuse shell to make sure someone didnt do the penny trick. Could be wired in reverse also. The shell is not supposed to be hot when fuse is removed. I have seen people make this mistake on the old porcelain fixtures. They are polarized.

You may have a sneak path from some other source, through the load, back to your supposedly dead circuit.

make sure you don't touch any coils when your around electrical devices. But yes, you can it depends on what you were touching. Don't touch any monitors they can hold up to 50,000volts so be careful
