Why autotransformers are not safe for supplying low voltage from a high voltage source?
Autotransformers are absolutely safe when supplying a lower voltage load from a higher voltage source, and are used to do so. However, they do not provide isolation. If isolation is considered essential, then autotransformers are not appropriate.
What is voltage grade of cable?
Voltage Grade of cables specifies the safe voltages which the insulation of the cable can withstand.
Are low-voltage systems totally safe Explain?
No, Their are no electrical systems that are totally safe. Elections harness electricity not control it.
What is the difference between the working voltage and test proof voltage for dielectric footwear?
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.
What would be the effect on the voltage level at the load if the distance between the electrical supply point and the load appliance is increased?
As the resistance in the wire increases due to the longer length the voltage drop across the wire resistance increases. This leaves less voltage across the load. To overcome this voltage drop usually a larger size wire which has less resistance is used. A safe nominal figure for voltage drop is to keep it at 3% of the line voltage.

Is 250V a safe voltage for the 220-240v appliances in India?
Simple answer..NO.
What is the purpose of capacitor in power supply higher than rated voltage?
The voltage marked on a capacitor is its MAXIMUM SAFE WORKING VOLTAGE. The capacitor will work in a circuit at any voltage lower than that, but it may fail at any higher voltage.
Are low-voltage systems totally safe Explain?
No, Their are no electrical systems that are totally safe. Elections harness electricity not control it.
Is it safe to have a 250 voltage device in a 110 volt current?
No. You will need a transformer to step up the voltage and you will possibly need to convert the plug.
What are the safe levels of direct current voltage?
60 Volts is generally considered a safe approximate maximum. In many applications that require 120 volts DC, the system will be center tapped so you have +60v and -60 volts so the hot to ground voltage is within safe limits.
Where is the voltage regulator in a 1986 Toyota Cressida?
probly buitl in to the altinator drive safe
What is the recommended safe voltage for electrical equipment on a building site?
It depends on the legislation of the country you are in.

Is it safe to replace a 20 amp 2 pole 120 vac with a 20 amp 2 pole 125 vac circuit interrupter?
Not a problem. The higher voltage rating of the interrupter just says it is safe and has been tested at that voltage.
What does the check gauges light mean on a 1994 Chrysler LeBaron?
It means that one gauge is not in the safe zone. Check the engine temp, oil pressure, battery/alternator voltage,It means that one gauge is not in the safe zone. Check the engine temp, oil pressure, battery/alternator voltage,
