[QUOTE="SPECIAL LOCATION, post: 538838, member: 250"] All cables fed from the same protective device are the SAME circuit.. The number of protective devices defines how many circuits you have, Not the number of cables.. e.g. 2x 6amp MCBs (or RCBOs) with one supplying 2x T&E, and the other supplying 3x T&E, are just TWO circuits, even though 5 T&E's leave the CU. A radial circuit can have numerous branches which may be at junction boxes, accessories OR the supplying protective device. (a branch off a circuit does NOT create a new circuit.) A "borrowed", (or more correct "shared") neutral, is where TWO circuits (i.e. protective devices) can supply the same piece of cable. Have you proved that your unknown neutral can become energised via more than one protective device? Multiple conductors into a single protective device does not constitute any code on an EICR.. unless the CSA are too small, or they cannot be securely clamped into the cable termination because there are too many conductors in there.. Your description is a bit too vague to figure out exactly what you have or not? [/QUOTE]
