Question: I'm in the process of wiring an extension to a domestic installation. The heating engineer has finished his work to move the boiler controls. He has used connectors and PVC tape to join his new supply and control cables. Is this satisfactory under the 17 Edition (BS:7671:2008)?
Answer: If a connection is made using a screwed connection it should be carried out using a junction box. This would provide additional mechanical protection around the connections. A terminal block and PVC tape is not adequate and, therefore, would not satisfy the requirements of BS7671:2008.

If crimped connectors are used, they again should be mounted inside an enclosure to provide additional mechanical protection.
