These pictures were taken in Mentone, Melbourne while shopping. As you can see, no expansion couplings were used and the saddles are galvanised steel.
As a result of exposure to the sun, the conduit has buckled for two reasons.
- No expansion couplings have been installed along the length of conduit and:
- PVC saddles should have been used to allow the conduit to slide within them while steel saddles have a raised "dimple" in the centre which grips the conduit. No problem with steel conduit but definitely bad practice to use them with PVC.
