16 may conrm that it is secure for the addition or change to proceed, relying on the certain setup and the nature of the addition or alteration, there might be a range of usefulness that require to be gone over with the client. For instance, new circuits may be called for but the existing consumer unit might have no spare ways or might not be a suitable kind of unit to install an RCD or RCBO.
