    Machine wiring standards

    EU customer will expect black for AC & DC power. Don’t use white it will cause issues. All DC control should be blue, AC control red. Orange for supplies from external machines, e.g. interlocking & special supplies, such as live with the main isolator off. Stick with these & your customer will...

    Machine wiring standards

    Darkwood, There is only 60204-1 then -32 for lifting equipment, -11 for HV machines, -33 for semi-conductor manufacturing machines, & -31 for sowing machines! A CNC machine such as a VMC or lathe will have a C-Type standard which will give additional information, but the generic requirements...

    Machine wiring standards

    Yes, but it is not as yet harmonised to the Machinery Directive! That could take another year, so even though the old version is withdrawn, strictly speaking, the old version is the one that should be followed as it is harmonised. Crazy situation I agree. There is also ISO 13849-1 for safety...

    Vacuum and compressor automation

    That depends on what it is, if you put it together and fit it, it's a product, which means it must meet the LVD. I am struggling to understand why this thread has moved from LVD compliance on to EMC compliance. The requirements of the two directives are totally different.

    We never got as far as EMCD, I was only going through LVD & MD, how did this get to EMCD?

    Vacuum and compressor automation

    That video is entitled EMC Directive, we’ve not even got as far as discussing this yet. What you state is correct wrt a fixed installation under BS7671, as an assembly of CE marked components. However the components that are used to put the installation together are not exempt from anything.

    Vacuum and compressor automation

    Avoidance is up to you, but remember, lots of products are already CE marked, and modifications to them eliminate that and put the "person" modifying them in the firing line as the manufacturer. This includes machinery repairs. Because I have always done this sort of work, when I went...

    Metal all the way, no brainer

    TBH, I would be saying that the manufacturers of these boards have a LOT to answer for, but, money talks, and they have bought their way out of trouble.

    Vacuum and compressor automation

    Yes you could, if you put a box of bits together without thought, for example a lighting panel, or a control panel for some extract fans, then you must follow the procedure and CE mark it, lighting would be to the LVD, and fans to the MD, Air con panels, MD, LEV panels MD, Heating panels, could...

    Vacuum and compressor automation

    Unless you are doing the work in the course of a business, and it is to be used outside your business premises. So in the course of your business, if you buy a Schneider panel and put a load of Schnieder control gear in it and a Schneider PLC to control the lighting in a customers premises, it...

    Vacuum and compressor automation

    An MK grid switch assembly is covered by MK, if it is done in accordance with their instructions. Devices such as a GET light switch and a BG patress back box, are designed and the standards are written in such a way that they can be assembled in an ad-hoc manner, as long as they fit together...

    Oh yes they blinking do, and they know the science, engineering and technology behind it too! They have a whole laboratory full of engineers and scientists who are specialists in their field. They will know the law, the standards, and the fundamental engineering and science behind what is...

    Vacuum and compressor automation

    If you modify something then you make a new product, unless it does exactly the same thing. but, remember, for example, that some products require type testing to meet the standard, if you modify such as to breach the type test, then that would be significant. It's nothing to do with sticking...

    Vacuum and compressor automation

    There is no simple guide unfortunately, but if you are placing an assembly of products on the market for sale, rental hire etc in the course of a business or to be used in the course of a business, then it must comply with the relevant product safety laws. A DOL starter must comply with the LVD...

    Vacuum and compressor automation

    Just realise that this caveat does not apply to the Machinery Directive, and that includes any electrical panels controlling the machinery. Also, forgot, if the company changes hands then there is the chance that that would be looked on as selling the equipment. Whilst electrical equipment...

    Vacuum and compressor automation

    If this is a stand alone control panel, then yes, and BS 7671 would not be the relevant standard. If it is for lighting it would be the EN 61439 series, and you must CE mark in accordance with the Low Voltage Directive. If it is to control machinery then the design and build standard would be...

    Devices plugged into BS1363 Socket Oulet

    The Chinese Export mark is an urban myth. Both the EU & Chinese authorities have stated such. The best explanation is that the so called Chinese Export mark is a bodged attempt at applying the CE mark.

    AFDD !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    Well, tell JPEL 64 that then because they require it, and they are allowing a MUCH greater energy with an SFDD to melt the cables and start a fire, so it is somewhy hypocritical & contradictory of them. Mind that’s not new, but it is also not of my doing.

    AFDD !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    You are correct, in that RCD's do not protect against series faults, such as broken conductors, we have MCB's to protect against L-N faults. However my issue is that we are only allowed the energy from a 300mA device in a parallel arc from L-E, but, 2.5A minimum in a series arc...
