    Hazardous areas - control voltage transformer earthing -

    CTE is not allowed in the machinery directive electrical product standard, so if it’s CTE then it is non compliant and probably illegal as it will not meet the EHSR’s.

    Hazardous areas - control voltage transformer earthing -

    Ignoring the hazardous area bit for a moment. You have a control transformer, which if it complies with the relevant IEC standards isolates the primary and secondary. Thus, you no longer have the concept of Live and Neutral with relation to the public supply. Yes, one of the legs of the control...

    Electrical test on 3 phase control panel

    In all the time I was with the NICEIC nobody there knew anything about EN 60204-1 their knowledge base lie in BS 7671 which is irrelevant and you cannot use it. It is not a grey area what so ever, it is clear cut. 7671 to the isolator. EN 60204-1 from there on. Unless one of the other parts of...

    Electrical test on 3 phase control panel

    However, However, that does not make the assembly legally compliant. CE + CE does not = CE. That is a fact. There is a lot more to compiling a technical file to prove that the equipment is safe and compliant than just ensuring you buy compliant parts, which you must. The testing required in...

    Electrical test on 3 phase control panel

    BS 7671 stops at the point your panel connects to the incoming supply. Everything else after that comes under the Machinery Directive. If this is new then you will need to do the tests in accordance with S18 of EN60204-1 and recorded for the technical file. This is a legal requirement and must...

    Bonding Control panel

    How do you split the circuits for maintenance and retain continuity in the protective conductor? Also when you reconnect you then have 2 circuits to test. I agree that bootlaces are designed for 2 wires, and a DIN rail terminal will take that and possibly 2 ends. However 13.1.1 para 3, second...

    Bonding Control panel

    Well I am more than willing to come in and deliver some bespoke training on 60204, 13849, 13850, 13855 & 13857, 14119, pretty much any of the other B-type standards, the A-type, and most of the c-type if there are any c-type standards that apply to your equipment. I spend most of my time these...

    Bonding Control panel

    If this is machinery covered by the machinery directive, and thus EN 60204-1, then the customer is totally correct. EN 60204-1 limits 1 protective conductor to 1 connecting point. Multiple crimped connections to the same stud are NOT acceptable. Multiple (2) protective conductors in a 2 way...

    Mcc panels and their Appropriate standard

    That is basically correct. BS 7671 excludes equipment covered by the machinery directive as this is covered by EN 60204-1. BS 7671 clause 110.2 xi is relevant. I don't think your use of the term MCC is suitable for a machine control panel, as an MCC would be something somewhat different, and is...

    Mcc panels and their Appropriate standard

    It is excluded from BS 7671 as it is a product, covered by the Low Voltage Directive and thus a product standard. However, they would fall under the (BS EN) IEC 61439 series. Not, BS EN 60294:2012 Measurement of the dimensions of a cylindrical component with axial terminations

    Three phase INDUSTRIAL fuse board recommendation

    My issue with Hager is that the breakers are only Pollution Category 2. So unsuitable for some industrial enviromnents.

    Why do soft starts tell you to set the overload at (delta FLC/1.73)

    DW, I was confused why the calculation thing came in at all! That is the reason for my post. These set ups are simply read if off the data these days and put it in the right parameter. The drive sorts it all out.

    Why do soft starts tell you to set the overload at (delta FLC/1.73)

    DW, The selection of soft start current depends on the design of the circuit and the motor configuration, remember that some motors are 230/400 & others 400/750 these days. Also, if the motor was in delta and had a FLC of x then you would enter the delta FLC in the soft start as long as that was...

    Outlook 365 Account chnages

    It never did exist per-se it is just that the Outook interface has been changed, and is now rubbish. If you go to control panel and then mail settings you can access the old fashioned window and means for editing accounts, ensure Outlook is closed first though. If the OP had rung MS support they...

    Motor control for chicken house

    1st thoughts in seconds. No control transformer, no control circuit protection, you mention emergency limits, no safety function, no emergency stop. What is the ISO 13849-1 performance level required? What safety systems are in place to prevent injury to persons if the remote control is...

    Motor control for chicken house

    I can, but not properly until I am in the UK realistically, I am currently in China doing machinery safety consulting, & it’s time for bed now, I am up early in the morning here. If you do this and it is not compliant, I hope you are insured, and not a sole trader, because, there are more laws...

    Motor control for chicken house

    If this is a workplace, and these gates are qutomatic, and could cause harm to a person, or livestock, or the system cause a fire, then full workplace legisation applies. These gates move under power, thus they are by definition machinery under the machinery directive. You are changing the...

    Contactor question - multiple inputs

    Remember that the LEV is a safety system. The machine controls if they have an e-stop have safety functions. Modifications to machinery must be carefully considered as they are covered by several pieces of legislation. This integration is easy to do, but not easy to do in compliance with the...
