I’m thinking of getting an electrician in to fit some down lighting in the kitchen. The problem is crossing the joists with cable without wrecking the ceiling as there is no access from the floor above.
If I took out small sections of plasterboard using an 80mm hole cutter from underneath the joists and then grooved the joists to a depth of half an inch the electrician could pass a cable through the groove then I could carefully nail or screw back the plasterboard avioding the cable from the plastboard in the cutter and then easily smooth over the cut.
Would this method be considered to be bad practice and would you carry out this job if you were given this job by a householder with the grooves already in place? Is there a better way to do it?
There will be a total of 9 x 10w downlights with firehoods crossing maybe 3 or 4 joists in 3 rows in a 10ft x 10ft kitchen. The lights produce the equivalent of 45W each with a lumen of 470.
