I'm running some conduit and have hit a problem I've never seen before... I'm using a Schneider box with the rubber grommets that can be replaced with a gland or bush, and I've found that the holes are slightly too large for the PVC bushes I've used in the past. On a 20mm hole or knockout these are usually pretty secure, but in these boxes I could wiggle one loose by hand (but not when clipped and screwed down).
Whilst everything will of course be securely screwed or clipped down, it just doesn't seem right. Has anyone else had this problem? What did you do, use a large washer, use a different type of bush or just accept that it's PVC conduit and won't be taking any significant force anyway?
