A shunt-trip breaker trips when voltage is applied to the coil. It does not self-reset when the voltage is removed, the breaker must be reset manually. The trip voltage can either latch or be applied momentarily, but must be de-energized before the breaker will reset.
A grounded neutral will be at earth potential. A floating neutral will be at a voltage dependent upon the voltage imbalance between phases, and the design of the transformer.

600v is a three phase service, where 347v is the L-N voltage (if grounded).
It varies by location and application. I will assume for this answer that we are talking low voltage (<1000 VAC): Grounded Wye Systems: 208/120 (Common) 480/277 (Common) 600/347 (Rare) Delta: 480 (ungrounded) 240/120 (grounded high-leg) 480/480 (corner grounded- rare and dangerous) The convention used above i.e. 208/120 designates the phase-phase voltage (208) and the phase to ground voltage (120). Some of the common Medium Voltage systems: 4.16 kV, 7.2 kV, 12.47 kV, 13.8kV
If meant ac signal then it is grounded so that the reference voltage is 0 & we get +ve voltage.
If they are grounded they get an electric shock or electrocuted. If they are not grounded or in simultaneous contact with the neutral wire, nothing. That's why birds can sit on a high voltage wire and survive; they are not grounded.

We often see the peak and trough (maximum positive and maximum negative excursions) of the sine wave considered as points of momentarily constant voltage. Those points are at phase angles of 90 degrees and at 270 degrees.
First off you should not be touching any high voltage source whether you are grounded or not. A pole isn't typically dangerous, it is the wires on the pole. A path to ground is required for a current to flow. Technicians working on high voltage power line often touch the lines and ensure they are not grounded when doing so, by using special procedures. That is why birds can sit on bare power lines without getting shocked.
In case of grounded load load is grounded and voltage is measured across it. while in case of floating load load is not grounded instead it is connected in feedback circuit.
There is normally no voltage on the neutral line because the neutral line is grounded. However, and this is always important, do not assume that neutral is grounded, nor that there is not an elevated voltage on neutral or ground due to a possible ground fault.

A grounded neutral will be at earth potential. A floating neutral will be at a voltage dependent upon the voltage imbalance between phases, and the design of the transformer.
If there is a short circuit between the transformer's high-voltage windings and its core (or any other metal parts, come to that) the fault will be recognised by the high-voltage supply's protective system, which will quickly disconnect the high-voltage line. For this to happen, the metal parts of the transformer, including its core and metal container, must be earthed or grounded to provide an electrical path back to the source of the high voltage.
If the electrical box is grounded, check with a tester, the "hot" wire will have a voltage to the the grounded box the neutral wire will not. If the box is not grounded, with the breaker supplying the voltage turned off, use a tester on the resistance scale to check for continuity between the wires and a cold water pipe or some other grounded medium. The neutral will have continuity between the wire and a ground the "hot" wire will not.
