    Single to 3 phase converter

    The biggest 1-3 phase inverters I use top out at 2.2kW, you're talking ten times that size. Plus, supplying 40A of 3-ph startup off a single line is going to fully use that 100A supply, then some more. Bottom line, if your client wants a 20kW lift motor, they need to stump up for 3 phase incomers.

    Motor control circuit

    I think you're reading too much into this one Marconi. The OP is almost word for word a question from my motor controls coursework, quite clearly being farmed out for answers.

    Anyone fancy a bit of domestic fault finding?

    Indeed, quite a bit packed in there. I'd be guessing several sets of outside lights on 24h timers or PE cells. Contactor/TOL sets on the RHS I'd say for irrigation, pool system, bore pump maybe. Various sets of heating for floors or different areas. Personally I'd have put all the extra bits in...

    USB Architrave? (20 chars)

    Not sure if Clipsal is used in UK, owned by Schneider so maybe. 240V is 240V after all. Architrave Plate Dual USB Mech

    Understanding manually calculating Zs

    235V and 5.27A are both to 3 significant figures. You could make the argument that 44.6ohms is consistent with your input precision.

    The future beckons, and demands 25 characters.

    I wanted to say thanks to everyone for their help and entertainment over the last few years. This last Tuesday I sat and passed my Capstone assessment, cue several months of passing forms between government departments and I'll be an officially licensed sparky! I'll miss the big yellow nametag...

    Trainees, Show Us Your Installs

    OK, it's been waaaaaay too long without some action in this thread. With the end of my training coming up soon (fingers crossed, Capstone assessment next month) I'm running my first major install for the boss. New machine in a poultry plant, remote IO to the main PLC. So far with a 2nd year...

    CAT 5 cable and connections tester suggestions...

    I use one of these and find it works well. Mine has four remotes so I can terminate several cables then test all at once.

    Newbie queation, low amps ?

    Yes, but only on the DC section. PV panels output DC, which then goes into the inverter and is output as AC either for use in your house or export to the grid. The best arrangement of panels is whatever works best with your inverter, each model has current/voltage limits on the DC input which...

    Veto pro pak xl to buy or not

    Same height, the LC is about 2/3 as long as the XL. My boss has a Tech LC, carries all he needs for general breakdown works. The extra space in my XL is mostly more specialised tools for install work.

    Veto pro pak xl to buy or not

    I use an XL. It's tough as nails, and as heavy as a box of them before you add tools. I wouldn't go back to my old Irwin totes, just be aware you'll not be able to skip arm day any more.

    Theoretically... cables must be fused down when a lower size cable is connected to a larger sized ca

    So, if we were to hypothetically say that I had already done this dodgy spur, what sort of hypothetical justifications should I use to hypothetically convince myself I haven't left a firetrap behind?

    single phase into 3phase trip switches/contactors etc

    They make 230V encoders? You certainly can wire single phase through a contactor, don't switch the earth. Not sure what you mean by 'protect' though, encoders draw so little power in normal use that it will be a smoking ruin before any thermal protection kicks in.

    Brain busters

    The permanent magnet will have distinct poles that the mild steel will tend to snap to. Apply the end of each piece to the middle of the other and see which sticks.

    Best deals for Wago

    I'll just put them on backwards, that should cancel out the upside down. AS3000 just says connectors must be of a design to prevent escape of single strands. We don't see a lot of wagos here it's mostly BP screw connectors; I'm on a bit of a crusade to convert my workmates I've got the wago bug...

    Best deals for Wago

    I've just had a look at these, and it seems they won't deliver to Australia. Would any members be interested in helping out with forwarding a parcel to me?

    Work in Sydney, Aus

    Transferring license won't be easy, make sure all your paperwork and training records are up to scratch or you'll be knocked back. Most UK transfers I've met over here started as TA's while they jumped the hoops. Wiring systems are a bit different. Almost no SWA outside of heavy industry...

    Power factor confusion

    You can't tell if a load is leading or lagging just from the KVA/KW/pf numbers. As the other poster has said it will depend on the nature of the load, with lagging loads being much more common. A specific power factor meter will tell you if your pf is leading or lagging too.
