    Any single pole double throw relay would do that, most relays are double pole anyway. Just depends on the load, I'd go with the octal relay. So thing like this will handle 2 Amps 2903315 | Phoenix Contact DPDT DIN Rail Non-Latching Relay, 24V dc Coil, 2 A | Phoenix Contact -...

    Good drill and driver

    I have to admit, I had an erbauer drill and it was ok for the cost until I started to abuse it, putting in tek screws and using large holesaws and drill bits, as I was doing a lot of industrial work , think the gearbox was on its way out so took it back for a refund or credit i for I remember...

    Good drill and driver

    When the drill comes it has a rather large handle which is about 500mm long that clips on, all I'm saying is I understand what it's for now, one black eye later! I'm lucky if I run down 2 never mind the 7 I have, not all 5Ah though, just 4 of them! 2x 4Ah and one 3Ah for the radio.

    Good drill and driver

    MILWAUKEE! I love the stuff if you can stretch to it. It just feels like quality, and the drill has that much power you have to be real carefully with it or it will throw you off you steps or smack you in the face! I've tried all budget level models in most brands but finally bit the bullet and...

    45kw motor and generator problem

    I know you did westward, just didn't get the opportunity to test during operation as I had to leave the isolator in place until their busy days were over and they could afford the inconvience of it possibly tripping. Understandably it doesn't look good if it cuts out mid ride. I think the C125...

    45kw motor and generator problem

    I turned the changeover time up to 10 seconds and it's been fine ever since however I have ordered a D type so will fit that for piece of mind.

    45kw motor and generator problem

    They have fitted a 4 pole isolator at the moment so that can operate, but ther is no protection for the cable and socket other than the MCcb in the generator with is about 400Amps

    45kw motor and generator problem

    The motor is actually supplied buy 2x 100 A and an 80amp bs88 fuses (not ideal) before the star/delta contractors and these are holding up, by the looks of it the 80amp is an original.

    45kw motor and generator problem

    I will do, this is a vast improvement in terms of protection on the usual set up, the sockets are usually straight onto the bus bars of the generators and the older ones don't have RCDs built in! So this is all quite hard to explain and hard to get them to understand why you need all this. They...

    45kw motor and generator problem

    So you don't think changing to a D curve would make a difference? You cannot really exceed the ride capacity as there are a fixed number of seats. There is also counter weights to off set the "boat" so I can't see where the load is really.

    45kw motor and generator problem

    Do you mean the lighting on that ride or the other loads on the generator, the other main loads are run from other plugs with their own protection all of which are fine, it's just when the motor changes to delta and the very odd time while the ride is operating, I am confident the generation is...

    45kw motor and generator problem

    I was wrong to say it slowed down, you could tell it Was working harder but it was coping fine, it drives the machine easily

    45kw motor and generator problem

    It all used to run off a 200kva with no issues, this was captured by my clamp meter with the max function it may have only existed for a second, the whole ride with motor running but no load (lights ect) was only drawing about 50amps/phase. It has been designed to run off a 125A socket from day...

    45kw motor and generator problem

    See pitcture When up and running, it wasn't this high when changing over, I admit i am not familiar with the standard but all the leads over 32A are covered by 300ma RCD and correct overcutrent protective devises and anything under this 30mA double pole rcbo, I'm sure there is more to it...

    45kw motor and generator problem

    You would also need to Integrate CT coil and earth leaks the relay as well as the MCcb, and there is no extra space. The generator does noticeably change speed when the motor changes over but no smoke The generator came from an sound and lighting company so I would imagine it implies with...

    45kw motor and generator problem

    I'm going to ask them to try the C125 now that I have increased the time and see how they get on, if not they'll have to try the type but not cheap, just wanted to here everyone else's thoughts.

    45kw motor and generator problem

    I know C120H is the range, well aware of that, it is a C125 MCB, you don't get 120Amp MCB. If it was an armoured to the machine you wouldn't require an RCD. I understand that it is a requirement under regulation 740.410.3 I agree the MCb is the problem, but harder to intigrate RCD...
