Electrician's essential vocabulary

EARTH FAILURE CURRENT

Current that crosses grounding diffuser in case of system failure.

DIRECT CONTACT

Contact with a part of the plant (eg cables, mosques, switches)

INDIRECT CONTACT

Contact with a conductor that is not part of the system due to a malfunction.

SINK

Metal clips straddles deeply in the ground used to disperse the current in case of failure.

FRUITS

Plant interaction elements such as switches, sockets, switches, housed in the appropriate boxes.

EARTH SYSTEM

The set of nodes (manifolds) and conductors and shutters intended to provide earthing for the protection of the electrical system.

PULLING

Operation by which cables are passed through the undercut corrugated pipes.

For this operation, you use the specific spring or threading probe.

DIFFERENTIAL or "SALVED" SWITCH

It is a special circuit-breaker that protects the system automatically removing voltage when it detects a minimum absorption difference (30mA) between conductor and neutral.

MAGNETOTERIC SWITCH

It is another special circuit-breaker that protects the system, which takes off when an overload or short-circuit occurs.

MAIN ISOLATION

Insulation of electrical parts needed to prevent lightning.

MASS

The part of the implant that is not normally live.

Can be live if main isolation falls.

MASSA ESTRANEA

Metal part not part of the system that comes into contact with the system for a fault or error (eg gas piping, hydraulic).

PLATE

Aesthetic finishing of the fruit box.

ELECTRICAL FRAME

It is the plant control center.

Installed immediately after the counter, it contains differential and thermal-magnetic circuit breakers.

The various lines control the parts of the system and can be powered by the manual switches on the panel.

PORTAFRUTTI BOX

Contains and houses switches, switches, etc.

CONTACT VOLTAGE

Electrical voltage to which the body is subject in case of contact with a live voltage system.

TOTAL EARTH VOLUME

Voltage on the mass.

Must always be zero, otherwise there is definitely a failure.
