I understand if you use a split 17th edition board you don't need a front end RCD... |
well if you installing to the 17th, assuming buried cables, socket outlets, bathrooms etc, then use use twin or triple 30mA RCD's, you wont need a front end RCD
the 30mA will provide additional protection and protection against fire
interesting how theres no mention of it in the 17th, cant wait for the OSG to come out!
