the power supply to my garage comes out just under the front room floor level which is about 8 foot up on the end of my house as i live on a hill the twin and earth cable 2.5mm then goes into a metal conduit box (round type) where it joins to swa cable 2.5mm via three 15amp connector blocks which are sealed over with electrical putty the swa then runs down the wall and under ground to the garage. does this meet iee regs or building regs. any help will be of great help as i have a snagging day in the house with the site manger in the morning .thanks jay.ps the gland packs used on the swa are internal type and not external type.
