Correct installation of circuit breakers
Hello! Please tell me if the rules for installing the circuit breaker are violated:
- There were machines with 20 amperes each, the master said that it was a lot, put 5 amperes each (in the apartment there is an electric stove with an oven, a washing machine with dryer and a heated towel rail in the same outlet, other appliances, a 2-room apartment).
- Connection to the electric meter - one wire stripped and curved is inserted into all machines (there are 4 of them) and connected to the meter (this wire is bare on top of the machines).
- Is the replacement of the circuit breaker working under voltage (additional fee for working under voltage 2000 rubles in my case)?
- Are adverse consequences possible with such a machine installation?
- Who issues a conclusion on the technical inspection of the circuit breaker connection (if the connection is not correct)?
Thank.

Hello! This was an introductory machine, please specify the nominal, 5 amperes cannot be, maybe a typo? Or on each of the groups? One or three phases? Where did the master come from to make a decision on replacing the denominations?
If the input automaton changes, this is work under voltage, if after the input automaton, it could de-energize the circuit. Work under voltage is the maintenance of electrical installations without relieving the voltage from live parts. Russian language - without disconnecting the power supply circuit breaker, circuit breaker or other switching devices. The correct choice of ratings of circuit breakers depends on what equipment they feed.
Yes, machines can be connected by one wire. But it is better that it be insulated. Although this is not regulated. Sometimes they are generally connected with tires in powerful cabinets. It was necessary to insist on isolation.
Adverse consequences are possible with improper selection of machines. They can knock out. Or if you touch a bare cable.
I am at a loss to answer the last question. But this is possible: What conclusion do you need? To commission the facility? Then you are in the organization that supplies you with electricity and will carry out the acceptance of the object.
