Your Solution for Building Installations
N-distribution without N-busbar (internal N-disconnection)
The N-conductors routed from the GFCI breakers are connected directly to the multilevel installation terminal block and commoned using an adjacent jumper when required.
Electrical circuit wiring without N-busbar
1. Each individual circuit phase coming from the circuit breaker is connected to the input of a multilevel installation terminal block and routed to the output terminal.
2. The ground foot takes on the ground (PE) potential of the multilevel installation terminal block and routes it to the output terminal.
3. The N-potential is connected directly to input from the RDC circuit breaker and routed to the output terminal.
4. The building circuit's conductors are connected to the 3 output terminals N, L and PE.
