RCDs 🇮🇪 Ireland
Which circuits need 30 mA RCD protection in Ireland?
Socket-outlets rated up to 32 A for general use need 30 mA RCD protection. Since I.S. 10101:2020, lighting circuits in dwellings do too. In practice a new Irish board protects every final circuit, often with RCBOs.
Sockets ≤ 32 A: 30 mADwelling lighting: 30 mA
Regulation: I.S. 10101:2020+A1:2024 411.3.3 (sockets) and 411.3.4 (lighting).
Study aid in plain English, not the text of the standard. Always check the current I.S. 10101 and your local rules. Electrical work must be done by a licensed or registered electrician.
