It is common that in any house, from time to time, we have
to solve some of the common electrical faults. Most are easily solved with
minimal knowledge of household electricity. Carrying them out will save us from
having to locate an electrician and the cost of hiring them.
Of course, the
breakdowns that we are going to describe below have an easy solution; If you
suffer a major breakdown or have serious doubts about it, our recommendation is
that you should hire the services of a professional electrical contractor.
The house has run out of power and the differential switch 'has tripped'
The differential switch has a double function. On the one
hand, it protects the people in the house in the event of a contact with electricity,
for example to avoid that, if a person touches a cable, they are electrocuted.
On the other hand, it detects if the appearance of derivations or high
frequency harmonics is taking place in the circuit and cuts the electrical
current automatically, to prevent damage from being caused.
What many
understand by one of the most annoying electrical breakdowns is nothing more
than a situation that can be solved quickly.
If the differential 'jumps' without the first situation
having occurred, that of direct contact with electricity, it may be a symptom
that, due to a fault, some of the receivers that are connected to a socket are
bypassed. The way to solve the situation is that, after checking in the
electrical panel of the house that the other magnetothermic switches remain
connected, all the receivers are unplugged.
The differential is then connected
again and the electrical appliances of the house are plugged in one by one. If
when activating any of them, the differential acts again, that is the one that generates
the electrical problem.
A short circuit has occurred
The deterioration of some cables or overheating when we use
several devices in a multiple socket can cause a short circuit. To solve this,
it is essential to know which devices were working at the time of the failure.
As the causes can be several, go ruling out possibilities; the short circuit
can be caused by the contact of a switch with the network or with a light bulb
in the event that it affects, for example, a lamp, or all the lighting.
If the
fault occurs in the plug that connects an appliance to the electrical network,
we must change it. It is advisable to check all junction boxes (always after
turning off the power, to avoid damage) to rule out that there are damaged
cables and that they need to be replaced.
If all the lights and all the
electrical appliances are checked, and the main switch "trips" again,
the problem may be located in the electrical circuit of the house, generally
because two wires are in contact.
The activation of the ICP has left the house without electricity
The Power Control Switch (ICP) is a device that automatically stops the supply of electricity at the moment in which a home exceeds the electrical power that its owner has contracted. It is a safety mechanism, mandatory in modern buildings, that 'cuts' the supply when it detects that there are too many appliances connected to electricity at the same time.
It is one of the most common electrical breakdowns, and has a solution as simple as disconnecting any of the electrical appliances while you are running. If the ICP jumps very often, it is because the power that we have contracted for our house is insufficient.
