Working Voltage is the voltage at which the boot is safe at. Test Proof voltage is what the boot was tested up to before it failed. However you must keep in mind that if you are in wet conditions that can significantly lower the rating of the boot. Also voltage does not kill you it is the amperage.
The dielectric material between the plates.
The dielectric,usually the insulator between the plates of a capacitor, can be overstressed by the application of too high voltages applied to the capacitor plates. The dielectric breaks down and a current flows between the plates until,either they are discharged, or an equilibrium is reached,below the working voltage of the capacitor. If the dielectric is damaged in this process he capacitor must be replaced. Some dielectric material self heal and can recover from an over voltage.
Strontium Titanate has a dielectric constant of 233. TDK in Japan makes Ultra-high Voltage Ceramic Capacitors using this as the dielectric material. Compared to distilled water at 76.7 - 78.2 (lowers as temperature rises). Types of glass can vary between 4 and 10.
what is the difference between cut- in and cut -out
A retarding voltage is what causes the electronic to shut down.
The dielectric strenght of a transformer represents the maximum voltage permissible to apply across the transformer insulation i.e. between the transformer winding to another part of the transformer, normally the chassis or another winding and without break-down of the insulation ocurring (e.g. arcing). The breakdown voltage of a transformer represents a voltage that exceeds its dielectric strenght and that causes breakdown e.g. arcing across the insulation.

no difference...

The distance between high voltage lines is governed by either a switching impulse voltage or lightning impulse voltage. The distance between lines, or lines and tower must have a high enough dielectric strength to avoid flashover at these voltage. Air can withstand a voltage of 3kv/mm.
Electronic charges will flow when a potential difference between the two locations, and an adequate path between them exists (with a low enough dielectric constant to allow the flow of charge - such as a wire). Electrons will move from here to there because there are "extra" electrons here, and there's some "missing" electrons there. Electrons have a specific charge. If you have "extra" electrons at one location relative to "missing" electrons at another location, you will have a negative voltage here, and a positive voltage (relative to here) there. This is called a potential difference (or voltage difference).
the difference between a voltage converter to a voltage regulator,is that a voltage converter,converts or changing the desired voltage to be used while the voltage regulator,regulates the input of the voltage amount not to excess to its inputs.

because voltage is the 'electrical potential difference'. since a "difference" can only be evaluated between two points so is voltage :)

Capacitor is nothing but a storage device. It has a dielectric media in between the two electrodes. the nature of the capacitor is charging and discharging the voltage.
