It's really as the title suggests, I need a LOTO box for a 16A plug for a job I've got guys on in a couple of weeks and I've never purchased them myself. Normally our LOTO involves locking off at a breaker/main power switch. This job is different and there's going to be generators on site and all it takes is for the wrong person to see an empty socket that will fit our plug nicely. All the ones I've looked at online are about 170mm, for those with experience will these fit a 16A plug properly?
