Frequently Asked Questions
What is the rule for installing an SPD?
✅ SPD (Surge Protection Device) connections should be as short as possible to minimize the voltage protection level (Up). The total length of connections to the network and earth should not exceed 50 cm to ensure effective surge protection.
How to Set Up a Surge Protector?
1.Turn off power at the circuit breaker.
2. Remove the old outlet.
3. Connect wires to the new surge-protected outlet per the manufacturer’s instructions.
4. Secure the outlet in the box and replace the cover plate.
5. Restore power and test the outlet.
What is the use of RCCB in Siemens?
✅ Siemens Residual Current Circuit Breakers (RCCBs) protect against electric shock by detecting leakage currents. If the leakage exceeds a set limit, the RCCB immediately disconnects the circuit, ensuring safety from direct or indirect contact with live components.
Where to Install RCCB?
✅ RCCBs should be installed in the distribution board (DB box) or circuit breaker panel to protect against current leakages caused by faulty wiring, ageing insulation, or defective appliances.
