As an electrician you definitely use precautions around electricity to avoid getting shocked or electrocuted. Here are some precautions I use:
shutting up
The main safety rule is to switch off at the mains before working on electrical equipment and wiring.
Mains electricity is nothing but main source of power in an installation. From the mains the power is then branched out to different end usage.
The mains lead in a strip heater serves as the primary power supply connection between the heater and the electrical outlet. It is typically a flexible insulated cable that carries the electrical current from the source to the heating element within the heater. The mains lead is essential for providing the necessary power for the heater to generate heat and maintain the desired temperature. It is important to ensure that the mains lead is properly connected and in good condition to prevent any electrical hazards or malfunctions.

The rising mains are essentially used in electrical distribution system in buildings two storied and above. It is basically used in indoor applications. Nowadays vertical type distribution is normally used as it is more convenient and reliable compared to rising cable system.

Due to an electrical surge can run through the power mains due to a telephone pole or electrical wiring being hit by lightning.

The standard household AC electrical power mains voltage in Greece is 230 volts, with a frequency of 50 Hz.
Rising mains come up from underground so they are less likely to be affected by weather conditions and they are not an eyesore.

The equipments power requirements, and the mains voltage. The output of the power supply must be able to deliver the correct voltage to the equipment, at the appropriate wattage. Additionally, it should be capable of operating on the supplied mains voltage and wattage.
Just like any other piece of electrical equipment - the phone company gets its power from the national grid. Additionally, they have emergency generators to maintain power if the mains fails.
230 / 240 volts

Everything that is plugged into the mains socket and switched on will use electricity even if it's a battery charger with no batteries in. So yes they do draw electrical power from the mains.
Because of emergency broadcasts by government departments. If you rely solely on mains-powered equipment, it may fail due to a power cut. battery-powered equipment is independent of the mains.
