• Electric fuses can be used instead of magnetic Circuit Breakers (CB).
In that case, select fuses with similar rated values as the CB.
• The Earth Leakage Breaker (ELB) mentioned on this manual is also
commonly known as Residual Current Device (RCD) or Residual
Current Circuit Breaker (RCCB).
• The Circuit Breakers (CB) are also known as Thermal-Magnetic
Circuit Breakers or just Magnetic Circuit Breakers (MCB).
Use wires which are not lighter than the polychloroprene
