Due to the fact that it at Amazon repeatedly Moreover, illegal FI types are sold I write here now a little info review for those who do not on what you have to look for in a FI knowledge.
Often sold here FI's are different from the pictures, so that does not recognize that it is a prohibited types. For this reason, check the FI receipt.
I try the review easy to hold so that it is understandable for laymen. I am aware that a lot is not described correctly, it would otherwise be more difficult to understand.
Functionality:
Fundamentally compares an FI the incoming with the outgoing currents (L1 to N or black wire to blue wire). If these currents differ (for example, when a person receives a shock) creates a magnetic field in the FI, which then triggers and the power turns off.
This is normally done at 30mA. A 16 A circuit breaker replaces a FI under any circumstances, since they released only at well over 16A and 16.000mA which kills a man with very high probability.
Rules:
In new construction, a 30mA FI (also called RCD) always obligation (since 2007)! For existing installations, there is a grandfathered. When modifications to the electrical system, a FI must always be retrofitted!
In the bathroom (and other wet areas) is an FI since 1984 duty but here is grandfathered. However, everyone should at least here retrofitting, since a current accident is here most likely and easily prevented by a FI (or mitigated) can be.
An FI may only be installed by a qualified electrician!
Examination:
Each FI has a test button. This test button must be pressed once every 6 months, as in the FI oils which can harden after a while when the FI has never triggered. When the test button is not pressed, it may be that in case of failure of the FI too late or not at all triggers!
IMPORTANT:
FI with type AC (in the next section explains) ARE PROHIBITED IN since the 80 outstanding at secured and. They exist, however, continue ON THE INTERNET (eg SECOND TO SELLER AT AMAZON) FOR SALE WHEREAS HERE'S CARE. PLEASE Chalk Electricians ATTENTION TO THE FACT THAT HE IS THE FI rechecked BEFORE HIM incorporates, otherwise no insurance cover is gross negligence AND WILL.
FI types:
Since I can not insert graphics I try to describe the icons. However, they are also easy to googling (Image Search FI types icons)
AC type:
AC sensitive
This FI is as I said in (almost) banned throughout Europe and may not be sold in Germany too! (See VDE 0100-530)
- Symbol: rectangle in which a sine wave is
- Tripping behavior: at sinusoidal AC fault currents
- Application: to throw away!
A type:
Pulse current sensitive
- Symbol: rectangle in which there is a sine wave over a second oscillation
- Tripping behavior: at sinusoidal AC fault currents and pulsating DC residual currents
- Application: home electronics, bathroom,
B-type:
universal current sensitive
- Symbol: rectangle in which a sine wave on a second vibration is located and a second rectangle by a line on a dotted line.
- Tripping behavior: at sinusoidal AC fault currents and pulsating and smooth DC fault currents (up to 1kHz)
- Application: Connectors are connected to the inverter (pump, washing machine,)
B + type:
universal current sensitive
- Symbol: rectangle in which a sine wave is about a second oscillation, a second rectangle by a line on a dotted line and a third rectangle in the kHz stands
- Tripping behavior: at sinusoidal AC fault currents and pulsating and smooth DC fault currents (up to 20kHz)
- Application: Connectors are connected to the inverter with high frequencies
F-Type:
Pulse current sensitive
- Symbol: rectangle in which a sine wave on a second vibration is located and a second rectangle with many sinusoidal oscillations
- Tripping behavior: at sinusoidal AC fault currents and pulsating and smooth DC fault currents and mixing frequencies other than the mains frequency
- Application: Connectors are connected to the inverter at high frequencies with a short time delayed trip
In short:
Upon receipt definitely check out the type and (symbol: a rectangle with sine wave) AC types informed immediately and Amazon with me please leave a comment that I can adjust the review.
