crabtree starbreaker

[waynelester]

hi,im after a little advice.a 5+5 consumer unit(star breaker),5 protected and 5 unprotected.the board has 3 un protected circuits ie 2 spare ways and 5 rcd protected circuits no spare ways.my problem is i need to add a new protected circuit.is it possible to move the rcd unit to allow an extra circuit.iv been told this cannot be done,an alternative would be to install a new rcbo but theses are expensive,also is it a no no to fit a type c breaker on a domestic system if its not required,thanks

Surely all the lamps on the circuit dont blow at the same time?...Likely they would have to switch back on the mcb in order to identify which lamp had gone!!...In which case your reason for not fitting a type C might be redundant......

Point taken but it was my boss who gets to make the executive decisions but as it stood in the end they were happy to keep the B type but like you say ..........
