I was wondering that because it's a 2.2kw machine, on something like a table saw with a 2.2kw motor you'll only just be able to run it off a 13A supply because there's barely any load whatsoever on start-up but with a PT you've got to take into account the large cutter block and the feed mechanism which need a lot of power to initially get moving.I can say that the Record PT107 on a 13 amp connection blows fuses on startup and needs the 16 amp connection as I have experienced.
That's a bit more pessimistic than necessary - AC Timber just outside Ely are closer than either of those, and the two branches of Ridgeons have a (more limited) range of joinery grade hard and softwoods, not just the construction stuff. Ignore the website; ask someone in the yard what they've got.sadly Cambridge is not a woodworker friendly area, there's no lumber yards, no timber suppliers, nothing! The closest are in Huntingdon & Peterborough but that's another story
I think Sedgwick still use separate motors on their planers, for different rates of feed at the turn of a switch.I don't know if there are any modern machines that use this configuration.

I'm not sure what the science is behind it but if you've got a machine that's available in single-phase and three-phase such as a Sedgwick MB the motors on the three-phase machine will be less KW than the single-phase one whilst out-putting the same or more power.
Hi Roy, I must admit I was assuming (a bad idea, I know ) that it was a twin socket on a 16A radial. It seemed the likeliest explanation. (Probably a bit of T&E 6” under the grass!)Hi there
As far as I am aware going by the 17th regs you need an isolator but it will depends on the installation, ideally you would have a local board and run the 16amp socket from a 16/20 amp protective device on 2.5mm radial via an isolator, not good practice to use the socket for local isolation. If you want to run a 16 amp socket from the ring then you need a fused isolator otherwise the protective device would be 32 amps, you do not have the protection afforded by the fuse in the 13 amp plug.
OK, but the cable is protected with a 16A protective device. so you can draw 16A from the twin socket shared between 2 plugs. (In practice you’ll get away a with a bit more depending on the type of protective device - type A/B discussion above). The 13A fuse protects the cable to the machine, not the fixed installation.Not going anywhere near any editions, but the advice above is not taking into account that the extraction needs to be running at the same time as the machine. So unless the extractor is plugged in at the house, the combination of both loads is way past any 13 amp plug limits.
