Like for single-phase networks, the average distance between the circuit breaker

panel and the last outlet connected to the electrical wiring must not exceed 200m. If

the PLC signal flows over the cables, goes through the circuit breaker panel, and

propagates over other cables again, then distance is greater than 200m, and the use-

ful throughput may fall.

The PLC signal also goes through the meter and may reach the electrical net-

work of the adjacent building, which can turn out to be useful if building a PLC local

area network between buildings is desired. However, this requires good security for

the PLC signal to avoid listening to the PLC network.

Wiring in an Electrical Network

The signal propagation may be affected by the cable section. To simplify, we can say

that the higher the cable section, the higher its attenuation.

Table 8.6 summarizes the various cable sections between the utility meter and

the circuit breaker panel.

Table 8.7 lists the recommended electrical conductor sections according to the

function of the device connected to this cable (NFC 15-100 standard). Therefore,

the cable sections that are mainly used are 1.5 mm² or 2.5 mm².

The Circuit Breaker Panel

The circuit breaker panel is the heart of the electrical network, from which all the

electrical wirings start. This panel is also the component protecting people from
