FAQ
-
What's the difference between an RCCB and an MCB?
An RCCB (ELCB) detects earth leakage current and disconnects the circuit to protect against electric shock — it does not protect against overload or short-circuit current. It's normally installed alongside MCBs, which handle overload and short-circuit protection; the two work together, not as substitutes for each other.
-
What does the 30mA rating mean, and do I need this sensitivity?
30mA is the sensitivity required for personal shock protection on socket outlet and bathroom circuits per most wiring regulations. If you're unsure which sensitivity your board needs, an electrician can confirm from the circuit design.
-
How many poles do I need?
This is a 2-pole unit, suited to a single-phase circuit (with neutral switched). Match the pole count to your incoming supply and the circuit(s) you're protecting.
-
Can I install this myself?
No — an RCCB is installed inside a distribution board and connected to live busbars. This must be done by a licensed electrician.
