ELECTRICAL SWITCHBOARD ASSEMBLY - DIN COMB INSTALLATION
There are several types of comb bus: unipolar or monopolar, bipolar, tripolar. These buses are also referred to in the market as single-phase, two-phase and three-phase, even though they are also used for earth and neutral.
The choice of bus must also take into account the load, that is, the current that will circulate through the circuit. There are copper bars for different currents such as: 100A, 125A, 150A, etc...
Other types of buses such as shielded, flexible, cylindrical and others will be the subject of another video.
Among the objectives of this video, we highlight:
- Introduce the Easy9 line comb bus and its advantages.
- Introduce the accessories: insulators, cable connector and protector for the bus pin.
We cover the following items throughout this video:
- The comb bus has this name because it looks like a hair comb and is used in derivation for circuit breakers.
- It is a single bus that guarantees the derivation of a power point for the other circuit breakers that are connected to it.
- There are models for single-pole, bipolar and three-pole circuits.
- This model from the Easy9 line supports a maximum current of 80A, that is, it guarantees the correct current distribution to the circuit breakers without overheating. Which cannot be guaranteed when the derivation is done through cables.
- It guarantees an ideal contact on the circuit breaker pole, in case of loosening the pole of a circuit breaker it does not cause a short circuit which would occur in the case of a cable coming loose and touching another point.
- With the cable connector it is also possible to make a derivation to another comb bus or even another circuit breaker, the terminal supports cables of up to 50mm².
- For spare spaces without a circuit breaker, there is an insulating protection that guarantees protection against contact with live parts, meeting the requirements of NR10.
