Its less the back box... That's a single point on a wall.... Not that structurally damaging... Like a core out the wall. But you run a horizontal cable route across a wall too deep you can do some damage.
Think the 1/6 the depth of a wall for a harizontal chase doesnt doesnt include back box depth. The idea is a harizontal chase could potentially cover 100% the length of the wall and if you cut that chase deeper than 1/6 the depth of the wall you could be effecting the structural integrity of the wall. Think of a lumber jack chopping a tree.
Is the back box considered a chase? I don’t think it does. If it does I vertically chase all my back boxes. 😉 I think it’s more talking about a chase itself and not the back box. A horizontal chase the full length of the wall can impact its integrity more than a vertical chase. So when chasing horizontal stick to the 1/6 and don’t worry about the back box.
Seems obvious, but cant you chase out the channels for the horizontal cables runs to 22mm and then chase the backboxes out to (whatever depth for those is needed), does that seem reasonable and within regs?
Stick with vertical chases .....and behind kitchen base units / which are part of fixtures etc ..clip horizontal low down..prob solved / all horizontal chases , are accidents waiting to happen...
Bulshit. I've seen loads of spiked cables... They were all on a vertical chase because that's where people drill walls. They don't generally drill at socket/kitchen counter level. Horizontal is fine and in no way more risky than a vertical chase.
Fancy chaser and vac still made a mess. Iv always used a grinder and Henry with top of a milk bottle (4 pint size) shoved on the end and it picks up most of the dust without looking like iv been down a coal mine at the end of the day. Still do my back boxes with a hammer and scutch, start of slightly under size and by time you finish it’s a perfect size.
@@pauldavies1693 best show your 'tutor' the big picture in the onsite guide that says it's absolutely fine and ask him how long ago he packed in plumbing...
Well it's not almost impossible it is impossible, if that's true then those regulations are obviously written by people who have not got a clue. I am assuming regulations don't apply to plumbers looking at those pipe drops where they haven't put anything on the wall, bare walls will react with the copper and eat through it eventually.
@@travoltasbiplane1551 a box is 25mm deep you can only cut 22mm, plus if you use mk edge you need a 47mm box for some of their accessories, and if a box being chased in a wall too deep is going to affect the structure of the wall, well I would say the place is shagged and needs pulling down.
@@acelectricalsecurity if you look at the building regs guide it's not about sockets. You can generally treat them with the same consideration as holes (i.e. it's in an isolated area). It's about cable chases where across a length it stands more chance of compromising structure.
@@travoltasbiplane1551 I don't know without checking but as I said if a chase compromises a structure then I would say the structure is shagged and wants pulling down.
@@acelectricalsecurity well not really... That's why they put limits on how much you're supposed to chop out. You can't say a 100mm wall isn't fit for purpose because you just took 50mm out of it on a horizontal chase and shagged it....
hi jimbo just curious I have the wall chaser plus hoover but it's in 110v not 230v but no matter what way I use it in domestic rewires it trips both plugged in to a transformer and socket was just curious are you just pluging that into a socket in the house to use......maybe I just need a high kva generater to use it would appreciate any feed back and maybe out to your subscribers aswell 😀
What KVA is your transformer, you're going to need at least a 3.5KVA, ideally a 5KVA or higher due to the continuous rating that's usually halfed. Most standard site transformers are either 1.5KVA or 3KVA.
@@Wayne-wo4ok Yeah definitely not enough, get a 5KVA one at least, ideally a smaler 7.5KVA if you can (very rare). Honestly if you don't need it to be a RLV 110v one then I'd sell it and get the 240 one. The 110v chaser and vac are both less powerful than the 240 one too.
