a while back I removed a backyard pond. I connected the old wiring from
pond to my shed. Three 10 ga wires - black, white and green. I picked up
a 30 amp breaker box from Menards and it has room for two 15 amp circuit
breakers. I am not an electrition but I am just putting in a couple of
lights, two outlets and one switch which I know how to do. The ground
connection is obvious but I am not sure about black and white wires to the
breaker box.... The circuit breakers have a place to connect a wire at the
bottom. The top end the circuit breaker connects to a terminal (not sure
that is right name) to which another wire will be connected. The black wire
is hot and the white is neutral. Which wire goes where?
The white goes to the neutral (center) connection and the black goes
to the other two. The box is designed for 240 volt input - black,
white and red with one fuse on each "phase" giving 120 volts on each
fuse.

And the only reason that's not a fire hazard is that with two 15A breakers on the same leg, he
won't be putting any more than 30A on the neutral -- and it's a 10g wire, so that's at least
marginally safe. I doubt it meets Code.

My advice to the OP still stands: hire a pro.
