Just a note on SY flex if you using it , it's not UV rated and the outer sheath will crack under sunlight over time and water will rust the braids. Thanks nice video
Gaz , I'm glad you haven't been using fancy tools, basics only. Some of us would say you should have been used some fancy brand stripers, cutters, etc. It doesn't matter what tool you have and you are using as long as the result is the correct one and always the same. Keep up with the good work mate :)
I wish I had seen this video last year the first time I saw one of these glands was the day of my AM2 lucky for me I saw another guy doing his so I did the decent thing and watched him 🤫
Thanks. Me, Matt and Joe try our very hardest to give all our learners the best possible start in the electrical industry. No always right but we try hard. Thanks again Gaz
Great video seems the gland manufacturers could look at a better way than the two washes maybe making one of them a cup washer similar to the type on motor terminals which would assist in holding the braiding in whilst Glanding off Maybe an additional lock ring to lock the braiding in prior to Insulation to the enclosure just a thought 👍
If you don't cut the braid short of the next braid exit of the gland, wouldn't you be able to exit one side and enter the opposite braid exit which would stop it from bowing out? I would assume it would save you a job of constantly pushing the braid back under the washers as you tighten the nuts.
Is it important whether the washers and braiding are on inside or outside the enclosure? Can gland be pushed inside then washers fitted within enclosure then locknut?
Hi there, I live by the coast and in coastal conditions I'd say don't cut too hard onto the galvanized braid because you'll expose the steel wire underneath the thin skin of galvo and the braid could rust at that point. Also apply some grease on any exposed iron/steel before you clamp it up. Man you wouldn't believe how quickly salt laden air will corrode espoused steel. Kind regards . . . Andy
I cannot find reference to that cable in BS7671. Can we actually use it on fixed wire applications? I thought you can only use it on portable applications like machines connected via commando sockets etc.
MysteriousDrJ this cable is not for final circuits.... when will City and Guilds and EAL catch up... the video is linked to an assessment my learners have to do. Thanks for commenting. Gaz 👍
GSH Electrical 👍. Last time I terminated swa was nearly 25 years ago, and I don’t remember seeing banjos in gland packs. Can’t recall any circuit testing after installation either......
Pls correct me if incorrect, but i heard that youre not supposed to using sy in the uk is now against regs as it doesnt afford adequate protection, was i misinformed?
I don’t use these glands I use pvc packing gland bring the cable fully into the enclosure strip back the cable and pull the inner core out of the braided armouring at the point of the cut of the outer insulation then screw the armouring up tight and slip on heat shrink earth sleeveing and heat shrink on or use just use large ordinary G/Y sleeveing, fit heat shrink over the point where the braid leaves the main cable and shrink it on or just wrap with tape. Connect the braid into the earth bar or crimp it and bolt to enclosure. A lot seem to just disconnect it and not connect at all. Commercial kitchen fitters seem to do this (at least hear) By the way the regulations don’t like you using this SY cable it does not have a CE stamp of approval (I don’t know why?) You have to put departure of regs in the test certificate if you use it.
I was recently looking an installation that uses YY flexible on cable tray. One of the electricians told me that it’s not allowed. I noted that the 18th edition mentions that flexible cables are not preferred and from memory states mechanical considerations apply but I could not find what the mechanical considerations actually are. So is YY cable allowed for installation with the U.K. regulation. It’s very common in the rest of Europe and it’s my understanding that our standards are harmonised standards. Sorry if this is a silly question I’m not a electricians but was just interested. I have asked 4 people and got 6 answers, Is it a gray area. Many thanks regards Chris.
Hi YY and SY etc are not recognised by our Regulations BS7671 this link should help from Napit and Voltimum www.voltimum.co.uk/articles/should-sy-yy-and-cy-cables-be-used All the best Gaz and thanks for commenting and watching
Hi. They make a glad that is designed to accommodate the braiding and allow it to be connected to earth as shown in the video. I have seen on site the method you described but this is not one I can teach my learners. Thanks for watching and commenting GSH Electrical
Ellison p I know quite a few sparks including myself who use stuffing glands as this sy glands are hard to get hold off. Even surelec tv use stuffing gland as alot of wholesalers dont stock them. Have to order but when you are busy and i have always stuffing gland in van. . David
Primary reason for not using stuffing glands: none compliance of 134.1.1 (not accounting for manufacturers recomendations) cable manufactures accound for gland and cable type tested arrangements, e.g. reactions to s/c fault and ingress protection?
@@lastsecondshez4683 thats a lot of worry for a cable that doesn't comply with bs7671 anyway :). Basically you'd be on your own if anything went wrong anyway so why not keep following your own agenda if you're going to use it. Stuff in gland and connectors will maintain ip rating and connect the braid just as well if not better than this gland in reality - whatever the manufacturers instructions might say. I know this cable looks pretty but why anyone would put themselves through using it is beyond me... It's a needless question mark.
Good question, on 50Hz its possibly ok to do that, but if you are running any high frequency such as stepper motors or hybrid servo motors (or even phase angle control) the 'pig tail' plays havoc with the harmonics and ground induced currents. The shield/armouring is best suited to a full cone and olive type gland, this reduces the harmonic effects.
Hi. For me the earthing ring is always on the outside so it can be seen on a visual inspection (EICR). I understand the modern earth locknuts are on the inside. Thanks for watching and commenting GSH Electrical 👍
Hi. The one connection you always want to be connected and the best it can be is the cpc (earth) hence the earthing ring needs fitting to the exposed conductive part. Thanks for the question and watching GSH Electrical 👍
Hi. Sorry it’s the SY job your watching and not my SWA one. Would you want a poor earth connection to the braided steel on SY flex which is often earth from one end only if it enters and insulated plug or insulated commando socket. The video is to help my learners and for their assessment an earth ring must be fitted (best practice). Once again thanks for watching Gaz
Thanks for the feedback. I suppose it is an improvement on not having one and can't hurt, I just wondered if it was mandatory to have one. Great videos btw, always helpful.
I am surprised that you say the shield of an SY cable can be used as a CPC. I’m not saying that you are wrong, but it was not aware that you could do that. In accordance with British Standards, where does it say that you can use the braid of an SY cable as a CPC?. The braid is made of steel, not copper, and is therefore less conductive than a dedicated CPC wire. Also, i’m led to believe that it is not required/necessary to terminate the braid at all (at least i hope that is the case 🤣).
Great video, it is a shame when Refrigeration engineers use this cable, they just cut out the outer braiding completely. Where is the BS7671 regulations for them.
+Andrew Saunders Hi. I am not a fan of this type of cable but it is part of the assessments we carry out at level 2... not covered by BS 7671 for current carrying capacity or volt drop 🤔. Many thanks GSH Electrical
Quite a good demo but please don't use roofing nuts and bolts to earth monocle ( earthing ring to our younger viewers!😀)... always use a brass nut and bolt.
Hi... your the second person to comment this view... we are working towards all the improvements we can in our workshop for 2018/19. Thanks for commenting and watching GSH Electrical 👍 (the quality of videos have improved since I shot this one)
Whilst the snob in me agrees that yes that would be better practice and a better job... :D I can't help myself to point out the steel fuseboard casing and the the steel braid of the cable... while we're getting steamed up about mixing metals at connections... What to do! :)
Great lessons! where is your school? Do you teach courses in electricity? Industrial, residential installations? How long do the courses last? I was interested, but I live in Brazil, I need to plan a season in the United States studying. What is the value of a course like this? I'm sorry for the bad writing, I'm still not very good in English, I had to appeal to google translate.

I see this SY cable used a lot from a VFD controller to the motor in Australia

Can the banjo not go on the inside of the unit. Braiding will still be armoured along with the housing?
I like it on the outside but yes you can 🦾👍
@@GSHElectrical thanks for the reply. Great channel keep up the hard work. 👍
Question. Can the earth banjo be fitted on the inside of the box?
Yes 👍
GSH Electrical 👍. Last time I terminated swa was nearly 25 years ago, and I don’t remember seeing banjos in gland packs. Can’t recall any circuit testing after installation either......
I've never wrapped the braid around between the two rings, just tighten everything up and snip off the excess.
Pls correct me if incorrect, but i heard that youre not supposed to using sy in the uk is now against regs as it doesnt afford adequate protection, was i misinformed?
What was that locknut spanner you used to tighten the nut?
Great FICA preparation, cheers
Not sure if this cheaper than swa ,but a lot faff to make off!

I've never wrapped the braid around the gland, not once. I just tighten the lock nut and snip the excess braid off. I feel I've let everyone down.
Can you sleeve the plait in green and yellow, use a stuffing gland and terminate directly into the earthing bar as a direct secondary cpc? If not why?
