Hi. I’m a spark with plentyof experience of domestic single phase but not much commercial, and 3 phase isjust a distant memory from college.
I have a customer who wants a 3-phase oven replacing. It’s on a suitable circuit with all-poleisolator so it should just be a simple like-for-like swap. I’m just slightly intimidated by the fact it’s3-phase and wondering whether there’s any traps to watch out for.
For example, the existing supply flex has two black coresand one brown for the three lives. Is itpossible to mix the phases up or are L1, L2 and L3 interchangeable? My understanding is that ovens normally justuse a single phase for each element so presumably not.
So, what I’m asking is, is this a simple straight swap or shouldI give it a swerve and stick to what I know?
Thanks
