(b) If the circuit’s protective measures are unaffected
(c) If the circuit’s protective measures and current-carrying capacity of conductors are unaffected by increased thermal insulation
(d) Special locations and installations are listed in Table 2
(e) Only if the existing circuit protective device is suitable and provides protection for the modified circuit, and other safety provisions are satisfactory
(f) Such work shall comply with other applicable legislation, such as the Gas Safety (Installation and Use) Regulations
