The electrical wiring of the house or apartment needs to be equipped with circuit breakers without fail. These devices will prevent ignition of wiring both at short circuit, and at overload.
Instruction
1. Define joint current which is consumed by all electric devices in your dwelling (without the chandeliers located on ceiling). For this purpose at first put their capacities, if necessary transfer the amount in watts, and then divide result into mains voltage expressed in volts. The result will turn out in amperes. On such current also choose automatic machines.
2. Learn from the electrician on what maximum current intensity your wiring is calculated. If it turns out that it is calculated on smaller current, than what is consumed by all your electric devices at the same time, respectively reduce also current on which automatic machines are calculated. Never turn on in network at the same time the devices consuming bigger joint current.
3. Remember that if connections between wires and terminals in sockets are weakened, your wiring is capable to sustain without heating considerably smaller current, than on what it is calculated. At deenergized wiring improve terminals in all sockets. Do not draw screws not to break the socket. If you are not sure of the forces, entrust this operation to the electrician.
4. Separately calculate the joint current consumed by the chandeliers located on ceiling, the same way as for other electric devices. Take the maximum allowed power of bulbs specified in passports of chandeliers into consideration even if bulbs of smaller power are actually twisted. Remember that the maximum power specified on the boss is admissible only for the boss as it is calculated without properties of the lamp shade. Therefore for the relevant data address only documentation on chandeliers.
5. Having chosen rated current of automatic machines, buy them. Installation them entrust electrics even in case you well understand this area. It is connected with the fact that only the staff of ZhEK can deenergize wiring to the place of connection of automatic machines.
6. Remember operation principle of time cut-outs. If current via the automatic machine only not much more exceeds rated, protection will work not at once, and only after warming up of bimetallic element. At short circuit the automatic machine will work at once. Never check either that, or another specially.
