Brief help from the industrial guys on required quals (415v)

Isolation training will deem them competent to lock equipment off.

It will not deem them competent to be reconnecting motors.

Yes it's not difficult to physically disconnect a motor and reconnect a new one.

You aren't going to find a short course to cover what it sounds like you want.

Thanks Rob, this was kind of my initial guess to be honest, as I suspected it wouldn't be that straightforward.

I think it will pay to get them on this safe isolation course anyway, then perhaps we'll go from there. We do have a good spark that subs to us so no issue using him until the fog clears.

Thanks for everyone's input, much appreciated.

Isolation training would still certainly be useful.

Just noticed your East Midlands. You can get them trained in safe isolation and re-connection and testing at the E-ON college in the power station Ratcliffe on Soar. Not sure if they will cover the mines and quarries side of it.

They can get the m&Q ACOP from the HSE for free. Or certainly used to be able to when I worked in them. This was 5 - 6 years ago now mind.

An they had gotten a lot more lax than they used to be.

Thanks David, should have thought of that actually, as we have had lads that crossed over from the power stations and I have seen Ratcliffe mentioned on a few certs previously. I will look into that, thank you.

Bear in mind that they may use an IT earthing system.

3 phase motors are indeed easy to connect but you must know what you are doing, there are a few different connection schemes to them.
recognizing the scheme takes a bit of learning and careful observation.
delta, double delta, wye, double wye, delta wye configurations, etc.
to name a few.
knowing how to diagnose a 3 phase system beyond basics is a skill learned over time.
training can be obtained for the senior maint. techs but its by far better to obtain a proper spark well versed in industrial to actually do the connections and testing, or at least oversee a proper training regime is the best recommendation!
proper isolation techniques is a valuable asset but for a maint. mechanic to isolate and test at the local disconnect (usually located at the machine) is about as far as they should go!
testing in a 3 phase panel without proper gear (ppe)and skills puts them in serious danger of arc flash injuries and should only be done by a competent spark who will have the proper ppe and knowledge to do so,
