Swimbo wanted a new decor light switch. I switched off the circuit at the
breaker board. While changing the switch I touched the live to either the
neutral or ground with a pliers. There was a good flash with sparks. I did
not believe this. I put a meter across the live and ground (and neutral).
All volts were zero. I tested again by connecting the live to the neutral or
earth with the pliers. No effect this time.

So what gives? How can a residual voltage be contained in a circuit
disconnected at the breaker?

I completed replacing the switch, switched on the breaker and everything
works ok.

Peter.

There is no residual electricity, you probably switched off the wrong
breaker or there was a second live circuit in the box

Agreed,

When you went back to the breaker box, did you find an additional breaker in
the tripped position?

A neon light or meter between each combination of 2 wires is a good CYA
test.

GFCI usually trip with much less drama at least hot or neutral WRT ground.
Hot to neutral may could tripped the breaker and left a GFCI still set.

Maybe somebody flipped the breaker back on. And are you sure you
flipped the right breaker?

I always introduce a intential short to check for such mistakes as
triopped wrong breaker or the dreaded this box contains 2 seperate live
circuits fed by 2 breakers.

better its a screwdrver frying than me flying across the
room............
