The differential circuit breaker works on the princple of summing up the
current amperage in every working wire. If the currents are summed up and give zero
result, this means that no current goes from the circuit to the
“ Earth ” . If the sum of
currents is different from zero and the value of differential current causes a threat of
electric shock, then the differential circuit breaker breaks such a circuit, including N
cable. The differential circuit breaker reacts to harmful current going to ‘Earth’, PE
cable, through insulation or human body. This breaker is equipped with test button
“ T ” and you should remember for your own safety to test the breaker once a month.
The inquires included in this sub-chapter only indirectly regards the safe
exploitation of installation on yachts. The main purpose is to show the
influence of electricityon the phenomenom and process of corrosion.
Each metal elements of the yachts which are under water are especially under
the threat of corrosion process. Cathode protection is used to protect underwater metal
equipment. This is commonly perceived as the most effective method of metal
construction protection in natural electrolytic environments.
The cathode protection is based on the connection of protected constructions in
case of our yachts it is mainly propeller) with a less quality metal creating the anode
pic p of the circuit where the cathode is the protected circuit. With time,
depending on the enviro-nment (high salinity and temperature helps the corrosion
process) and other factors, the anode is getting smaller, it just melts down.
