How to Install Simple Single Phase 127V Panel
How to assemble a simple 127V single-phase power panel with DR to protect several circuits at the same time.
This 127V switchboard has a general breaker, one (DR), breakers for lighting, two for outlets and one for shower.
The frame can be built-in or superimposed, depending on your installation.
How to ASSEMBLE a 127V SINGLE-PHASE DISTRIBUTION BOARD - with DR and DPS
Do you know where the “heart” of your electrical installation is? that's right, every installation has or at least should have, which is exactly the circuit distribution board the "heart" of your electrical installation. This is where the protection devices are located, such as circuit breaker, SPD and DR. Thinking about the importance of the distribution board and the difficulty and doubts related to the QDC, we prepared this article, explaining in detail how to assemble a residential distribution board, come on guys!
What is a distribution board?
The distribution board is mandatory in all electrical installations, as it is where the protection devices of a residential, industrial, commercial, etc. electrical installation are located. The distribution board is responsible for storing, protecting the protection devices and distributing all the circuits in the installation.
We can highlight that the distribution board is also known by many people as a general board, breaker board and QDC (circuit distribution board). The distribution board can be found in PVC or metallic, in homes the most common is PVC, as it is cheaper. The iron QDC is more used in industry and in the assembly of controls, both the PVC distribution board and the metallic one are found to embed and superimpose.
What are protective devices?
Protection devices are responsible for protecting your home from any problems such as leakage of electrical current, short circuits and overvoltages. The devices responsible for this protection are circuit breaker, DR (residual differential) and SPD (surge protection devices), they are the main components of a distribution board
Components of a distribution board.
The main components of a distribution board are neutral and grounding bars, DIN rail, circuit breaker, DR (residual differential) and SPD (surge protection devices). There are other components, such as contactor, relay, multimeter, among others, but which are not widely used in homes.
Circuit breakers
Circuit breakers are devices that protect against short circuit or overload, being essential to prevent accidents and even fires. There are different models of circuit breakers such as DIN and NEMA, and they can be single-pole, two-pole or three-pole.
DR (residual differential)
The DR is responsible for protecting against leakage of electric current, thus protecting against electric shocks. There are two types of DR, which are the IDR (residual differential switch) and DDR (residual differential circuit breaker). The DR also have curves B, C and D, and several models such as bipolar, tripolar and tetrapolar.
SPD (Surge Protection Devices)
The SPD is an electrical surge protection device, important for protecting electrical and electronic equipment. Electrical surges happen because of atmospheric discharges that affect electrical networks and anomalies in the electrical network, such as the activation of large motors.
Din rail and neutral and ground busbars
The DIN rail is used to fix the protection devices. Neutral and grounding buses are a safer and more organized way to distribute electrical conductors and interconnect all conductors at a single point, thus facilitating future maintenance and ensuring that all conductors are securely fastened.
