FAQ – ETEK EKL6-100B Type B RCCB

Q1: Does the EKL6-100B RCCB support reverse feeding (bottom supply connection)?

A: Yes. The ETEK EKL6-100B Type B RCCB supports reverse feeding.

The power supply (Grid) can be connected to either:

• Top terminals: 1, 3, 5, N, or

• Bottom terminals: 2, 4, 6, N

There is no functional or safety difference between top or bottom supply connection.

Q2: Will reverse wiring affect the protection performance of this RCCB?

A: No. Reverse wiring will not affect the protection performance.

The EKL6-100B operates using an electromagnetic tripping mechanism, which means:

• Residual current detection remains accurate

• Tripping characteristics remain unchanged

• Safety and protection functions are fully maintained

Q3: Is reverse feeding safe for a Type B RCCB with internal electronics?

A: Yes. Although Type B RCCBs include internal electronic components for residual current detection, the tripping mechanism itself is electromagnetic.
Therefore, reverse feeding does not impair detection, tripping, or safety performance.

Q4: Are there any special precautions when using reverse feeding?

A: When using reverse feeding, please ensure:

• All phase conductors and neutral are connected correctly and consistently

• Terminal tightening torque complies with the installation instructions

• Installation follows applicable local electrical standards and regulations
