Ladies and gentlemen, welcome again to our weekly
podcast. We are here on Electrical Life. Today
in this session, we’ll be discussing some electrical
doubts we’ve been having about fuses and circuit
breakers. I’m here with Diego. Hello, good morning.
Yesterday, my sister called me because the
circuit breakers were turning off all the time and
she didn’t know what happened. And I’m
here to… Okay, I got you. This is probably because
of three possibilities of tripping of the circuit
breakers. The first one is the overload. So
in that case she will have to check the amount
of devices that are connected and turned on
at the same time on the house. Because in which
in which there are too many devices,
they will be producing an overload. Yeah, I
think that’s not a problem, because it has normally
five or six electrical devices and it has
not consumed at all. Okay, in that case we’ll
be discussing the probability of a short circuit
which basically it consists of two hot
wires touching themselves. In that case it
has an increase, a peak of increase of temperature
and they blow, they get blown.
Also I think she could see something about the circuit
breakers because they can be broken and she probably
have to change it. Yeah maybe because even circuit
breakers even though they don’t have to be replaced
not as fuses obviously even though they have
to get like a maintenance period each three
years I think or so Maybe she’ll have to
call an electrician and he have to test them.
Saying to her that. What are the tools that I
need for changing the signal breakers? It’s
not too complicated but every electrician knows
it, it’s only a star or a flat screwdriver
and if you want to check the continuity you
could need a multimeter as well but it’s not
necessary. By the way, I just realized I forgot
the matter that it could be a ground fault
also. A ground fault? What’s that? It consists
of basically when a hot bus touches a ground
wire, or also when it touches the cover, or
the metallic cover, of a device, of an electrical
device. In which case, the current goes into
all the ground and touches the whole amount
of devices of the house. And obviously, it’s
an overload. And the circuit breaker will be
tripped.
By the way, I was talking with my sibling last
night and we were discussing the advantages and
disadvantages (pros/contras) of circuit breakers and fuses.
Do you know something about it? Oh yeah, normally the
fuses are cheaper but you have to replace them when they
blown because they can’t be turned on again.
And on further it nor mallly becomes more expensive
Tan taking circuit breaker
breaker that’s in one
buy, it’s expensive but you can turn on again
if it turns on. Ok, so then we can say that
circuit breakers are much better and much more
rentable at long term, right? Yeah, that’s
right. Ok, perfect, perfect. Also the fuses
have a… a more difficult installation because
you have to turn on or off the current to change
one. Okay, okay, I didn’t know that. I thought
that it was the same thing, but okay. By the
way, are they like…
more effective the circuit breakers than the
fuses or they are the same? Yeah, normally
a circuit breaker is more effective because
you can…
a lower time to reacts with a sort of kick with
another current than the fuse. Okay, okay,
okay. That’s been enough and more than enough
for this session, ladies and gentlemen. So
see you the next week. Have a nice day.
