    4 or 5 pin plugs for 3 phase supply from inverter?

    You are missing one small but vital point here. At no time did I say "I've just bought a 3 phase bandsaw and an inverter, can you tell me how to wire it?" I asked about the use of 4 and 5 pin plugs and sockets, from a practical point of view. I'm sorry I have caused such a stir but there have...

    4 or 5 pin plugs for 3 phase supply from inverter?

    You made an assumption about how I would wire the on/off. Sorry, you assumed wrong. I'm not an electrician. Just looking for some advice. Feels to me that some find it more rewarding to knock people down than offer help. You might like to consider that some people have enquiring minds, they...

    4 or 5 pin plugs for 3 phase supply from inverter?

    The control connections will be used for on/off, i just don't require speed control.

    4 or 5 pin plugs for 3 phase supply from inverter?

    I'm happy with stop-start, no speed control. There are several wiring options in the manual. The saw is probably more than 60 years old so no braking. I considered braking and a resistor is available. Someone I know said he had problems with resistor braking, it caused the invertor to go into...

    4 or 5 pin plugs for 3 phase supply from inverter?

    You are right, and maybe the most important factor is that none of you know me or my capabilities. Warning someone to be careful is one thing, "funny" comments like "I can smell a bit of 'boom boom' in the air." are not to my mind useful at all. I was advised to use screened cable by the...

    4 or 5 pin plugs for 3 phase supply from inverter?

    So you have someting against me learning? the only error I seemed to have made so far is not appreciating that I need screened cable between the motor and inverter. Luckily, by seeking help, albeit socially distanced, i discovered before ordering.

    4 or 5 pin plugs for 3 phase supply from inverter?

    I have no problems wiring the inverter but I have never used 3 phase. This is the junction box on the saw and how I believe it should be re-wired. But I am confused about the neutral? I can buy 4 pin or 5 pin ind plugs/sockets and I just really wanted to know which I should use and why.

    4 or 5 pin plugs for 3 phase supply from inverter?

    The plate says 260V 5A in delta. I assume 1.5mm is sufficient? Any reason to use 2.5mm?

    Cleaning supply to a WIFI antenna

    It isn't up to the job, they have already changed it to max 70mm(2) So I'm stuck with it, and I only have a 5kw supply. I thought of a UPS but wasn't sure how they worked and if they would actually even out the fluctuations. is an "online UPS" different from a std UPS?

    4 or 5 pin plugs for 3 phase supply from inverter?

    Its a 60 year old dual voltage. 3 plus earth is all the bandsaw needs. I'm just curious as to why the neutral and if the 3P N and earth is just the lastest version?

    4 or 5 pin plugs for 3 phase supply from inverter?

    I have recently bought a 3 phase bandsaw for hobby use and acquired a single phase to 3 phase inverter to power it. When I looked at buying cable and plugs/sockets for the supply I didn't know if I should choose 3P + earth or 3P N + earth plugs and sockets. What is the difference and which...

    Cleaning supply to a WIFI antenna

    I have recently installed wireless ADSL, the phone company dont offer ADSL and the satellite ADSL system I was using is too expensive and the latency was a problem. The antenna keeps resetting, up to 30 times a day, and the suggestion is that voltage fluctuations are the problem. I do have a...

    What do I need to know to calculate size of single phase motor?

    Can you tell me the model number so I can take a look?

    What do I need to know to calculate size of single phase motor?

    What would happen if the motor tried to deliver 5A and the VFD was only 4A. The saw is for hobby use and I hope wouldn't be pushed too hard.

    What do I need to know to calculate size of single phase motor?

    The bandsaw is far too old There is no info I can find

    What do I need to know to calculate size of single phase motor?

    I think it may be a tad small. I think I need 5A output. But to be honest I don't really know enough to be sure.

    What do I need to know to calculate size of single phase motor?

    Thank you. I thought a quality VFD would cost more. I guess £55 is a budget version? Do I assume from your earlier post that the wiring to the motor, you mentioned 260, would also have to be changed with a VFD? I don't understand star and delta wiring but looking at the the plate I have shown...
