the regulations states you cannot make a joint in a coupling ... so the couplings must go ... so you what you do is use a 25 mm pipe and epoxy the pushin glands in the 25 mm pipe ... no couplings ...no elbows .. no TEE- pieces
or use a heat gun and heat up the end of the 20 mm pvc pipe ... it makes it soft ... push the gland into the end of the pipe ... problems solved.
I am sorry but i am gonna dig my heels in on this one ... I WILL NOT BEND OVER and allow to be robbed of R80 for a joint when i can make a joint for under R5 ...i have just installed 10 x 10 watt flood lights ... it would have cost me R800 to extend the the ridiculous 10 cm long cable supplied with radiat flood light ... R50 or R800 ... i am gona take my chances with my pvc pipe
Dont forget the weather drip on the wire if you install it outside and make sure the glands are tight and seal the ends.
