Splet07. maj 2010 · Having the RCD at the house-end means an earth fault on the garage power would take out the lights so you may want an emergency light in the garage if using circular saw. Some people run SWA all the way to the house CU, but in some cases this can be very difficult (solid floors, space). There is a uk.d-i-y FAQ available - worth reading. Splet1. Determine the diameter size of the tubing. Measure the diameter of the underlying materials to be covered - at the widest part. Select tubing that is 20% - 30% larger than this measurement by referring to the product’s datasheet on the Website 2. Determine the shrink ratio of the tubing.
