    Electrical Question - 3 Phase Motor starter

    MP, Not a problem giving you advice. You can't worry about where it may end up Caveat Emptor and all that. As you are not a dealer, you would not have the responsibility of ensuring it meets legislation if you were to sell it into a business, it would be the buyers responsibility to ensure it...

    Workshop Design

    Dibs, It would be my preference to bring the cable through a duct in the floor slab also, however, there is nothing wrong with bringing the cable up the exterior of the building and then as i said entering through the soffit area. An FMEA should be done as a routine part of any design exercise...

    Electrical Question - 3 Phase Motor starter

    Yes I do know how to spec up the correct starter! Fiorst though please give us some more info on the machine, make/model? I have seen this before it is common on the Wadkin BT series, & I don't like it, and, it does not comply with current legislation for machinery used in business undertakings...

    Workshop Design

    kingcod, If you utilise that box then you must be careful as you can experience plastic deformation of the body of the box, allowing the cable glands to loosen, this can allow a corresponding increase in earth fault loop impedance and a reduction in the sealing properties, i.e. IP rating of the...

    Workshop Design

    Dibs, I am qualified to practice in countries where the term engineer is protected in law I can assure you as this is one of my pet hates also! I won't list my qualifications, but I did an apprenticeship and then carried on to get letters. I was made redundant from a design/applications...

    Issues EB PKF 255 /2.5 wn - starting capacitor

    This is normal for a motor cap. The cap creates an artifical 3rd phase thus you are no longer comparing voltages with respect to earth, which is where your 240V, which is now officially 230V by the way! Comes from. Increased voltage and also temperature as you have found out reduces the life...

    wadkin lathe motor

    wallace, Is the shaft not coupled to the motor? If it is then a mod could be done to link the new motor to the old shaft. Other option is as has been suggested a 1ph to 3ph conversion of some sort. I'm not familiar with static converters, I know rotary converters, and inverters, as i used to...

    Sharpening Planer Blades

    Shame guys, I used to run a Saw Doctors, but the 80% reduction in our business when the crash hit put a stop to that! No machines or anything left. I do have a few contacts still in the trade though.

    wadkin lathe motor

    wallace, A 1ph 6 pole is available, however, the cost is not nice! You are looking at the other side of £300 probably plus VAT! Then you would need to look at whatever mechanical mods are required to fit the motor, possibly mounts, pulley bore/keyway, it may be cheaper to get a new pulley bored...

    wadkin lathe motor

    That sounds like an imperial motor, so some tweaks will be needed if you decide to replace it with a modern metric version. You'll want a foot mount B05 or B35 depending on the room you have. 1.5HP = 1.1kW approx. 960 rpm will be a 6 pole motor in either 80 or 90 frame size probably. You will...

    Workshop Design

    Why add an additional joint into the cable? IF you use a screwed joint, such as a "chocolate block" this has to be accessible for inspection. (Regs) You are addiing additional impedance into your supply cable which reduces its "performance", it will increase volt drop and earth fault loop...

    Workshop Design

    I would NOT put a "joint box" on the exterior of the building guys! By all means take the SWA up the exterior of the building, I would take it up to soffit level and into the building intact then run the SWA to the point where you are going to locate the consumer unit. How you joint up from...

    Floor Access Hatches

    Apart from the Trend unit, there is also the Armeg Solid Boad Cutter & you cany buy ready made blanks, though that is not cheap either. I can't post links as my account is not allowed as I am new I guess! The SBC is typical of what us sparks use to make these sorts of openings. :D Hope this helps.
