PURPOSE: A substrate of a cabinet panel is provided to prevent a flame from one wire to another by installing incombustible partitions between terminals and wires. CONSTITUTION: A copper wire holder(20) is installed on the midsection of a substrate(40). The substrate is composed of a first substrate(40'), a second substrate(40") and a third substrate(40"'). A main circuit breaker is installed on the upper part of the copper line holder. A sub circuit breaker and an earth leakage breaker are installed on both sides of the midsection and both sides of the lower part of the copper line holder. Terminals and wires of the circuit breaker are separated by a partition(42). |
