I do alot of remote e-stop on conveyors.
Awesome work. Ty for videos.
You are welcome Dwayne. Any tips you can give would be great!
I like your videos they have really helped me in my professional life. I look forward to seeing more. Thanks for your content.
Glad you like them James!
Your have great videos with great knowledge. I'm on a project, explosion proof, using safety relays. Arc happens inside the cabinet.
Yes with explosion proof applications, you need to have every I dotted and T crossed!
Thank you alot Engineer... a very interesting topic
You are welcome.
I enjoy your videos.
That is the best complement you can give Jack!
When I install e-stop at several locations I wire lights together to show there is a e-stop energized no matter were you are standing at the machine.
I go back and forth on this. It does make it clear that there is an emergency stop pressed but having the individual one illuminated lets you know specifically which one is. An additional light in a position where everyone can see letting them know that an estop was pressed would be better but everything had to be out of sight on this one to prevent damage.
Could you do a video about how to select a proper motor overload protection circuitbreaker for a lets say 3kW 3fase motor? Wired from the wall to the motor 10 meter? And also what wire or cable is used for that 10 meter cable. And what type of wires do you use in the panel/cabine on the overload protection/circuit breakers . I understand one needs to calculate first Ib then incase of a motor protection there is an In current, the current that trips the motorprotection. You have type B and type C motor protection devices. what to select? Where on internet do i find the table. And what is your opinion about all the layout and holes pre-calculated by an other person like an E-Plan drawer/Electrical engineer ? Sometimes this Engineer is more a E-Plan CAD usage person then a panel/cabine wiring engineer. I am in the Netherlands, and i switched 2 years ago to E-Plan drawing, but i cannot show the experience to new companies, i am looking for a job and it is very hard to get a chance also i am 40plus, so i cannot start back in the production room wiring these panels, which i did in 1995 at school and practical year at real automation companies. But that was long time ago! Other question do you use flexible wires that consits of small copper wires for the motorprotection wiring or is it a wire with a massive core ? Like people use in houses. PVC- isolated wires. I see you will have a live session so maybe you can handle / answer some of my questions.
That might make a good lesson, let me see what I can do.
@@TimWilborne especialy. European style based on a motornameplate of an induction motor given 15kW on the plate switching from star to delta with 3phase European voltage. Sometines the plate gives I 1/1 which is the current at max load. That might be the same as current full load Ampere ? That might be the current fir 1 phase? How to calculate the Inominal?
Could you do the whole procedure with a motor plate from the European markt? Assume the start procedure is starcirciut to deltacirciut and the protection device may achieve that or a external circuit. And this motorplate is used crushtymks.com/images/electric-motor/the-basics-of-built-in-motor-protection-for-engineers-beginners_2.gif the bottom one in black, with 50 Hz. and you may use docplayer.nl/8187348-Normen-formules-tabellen.html Also explain what is Ib in Europe this is used as design current, Inominal, Iphase current, The American motor nameplates gives the Full load Ampere, which is proberbly the Maximal load I 1/1 on European plate ? The Full load Current(also known as Full load Code) is higher then FLA and is selected from table from an American engineering book, from Kw or HP to FLC Ampere. But i would like the European/English design/size procedure for a Motor protection Circuit Breaker. And why do you need Fuses as extra before an Motoroverload protection device? These things focused on the type of Motor most of time squal / async motor. Async ponits to some slip, to the rotation that is slight lower then the synchrone rotation? whatever the synchrone rotation may be. Other questino is a VFD possible on a synchrone motor which normaly have 1 constant speed? The Cable calculations /procedure , and complaince with the dropdown allowed maximum is understandable procedure and is also in the 8187348-Normen-formules-tabellen. But the Motor overload protection, is difficult, also with a external star to delta circit.
Great video Tim. Do you have the schematics available for this build? Thanks!
No, we don't have schematics available for our custom builds.
@@TimWilborne No Problem. Do you mind me asking, which brand of MCCB and door kit did you use? Thanks.
