We had a "lock out- tag out system" when I use to work for a large semiconductor company in Ireland. A great system which worked really well & provided you with that security. You always had that niggling worry that's always in the back of your mind that some unsuspecting person could accidentally turn the power back on. When I went back to domestic sparking I always tried to recreate it, as the same safety standards were just not there. Great to see this device being introduced.

Actually you won't get shocked if you touch that probe with your hand. The internal impedance of these testers is too high for that. Otherwise you would trip the RCD/RCBO when testing between line and CPC. If the tester is damaged and that internal impedance is no longer given, the tester would indicate weird voltage values. Some proofing units will give you a full test cycle with different voltages. A different thing is if you have a tester with a load connection, but this load connection is only applied when pressing two buttons simultaneously, and only for the time both buttons are pressed. And that load connection trips RCDs/RCBOs. Still good practice to do so. But on a three-phase system it becomes a bit weird, because you also have to test between the lines, so there is no least dangerous in that case. Here in Germany the safe isolation is fixed in our regs for decades in the DIN VDE 0105, called the "five safety rules for electrical work" 1. isolate circuit 2. prevent reenergizing 3. ensure the circuit is really dead with a properly tested 2-pole voltage tester 4. earth and short-circuit all conductors (only on overhead lines which are usually not insulated, and voltages above 1kV) 5. cover up all exposed live parts next to your working area (that is mainly for work areas like transformer stations or industrial environments) So for domestic usually only rules 1 to 3 are relevant. Instead of using a proofing unit you can also use a known functional live circuit instead to fulfill that regulation. But sometimes you don't have the luxury of having one in the area, so still a good idea of having a proofing unit. Also a tip: Always use your own lock, never a provided one by a colleague or the customer! You don't know who else got a copy of the key for that lock.

I had an incident recently in a refurbished commercial building. The building had undergone extensive refurbishment that included a rewire. The incident involved an installed motor which now had a new feed from a different DB, the electrician had connected the new feed but hadn't removed the old wiring which had just been cut-off and left. Because I needed to renew some low-voltage control wiring that ran through the same flexible conduit as the old feed I went to remove this cut-off power cable, only to find out the hard way that the electrician had left it connected at the load end so it was now back-fed from the incoming side of the motor isolator. Of course I should have turned-off the relevant MCB in the new DB first, but it never occurred to me that a qualified spark would connect the new wiring to the isolator without removing the old wiring first. The moral of this story is never assume that the other guy, however well qualified, is going to do the job properly.

Using a tone generator would involve more disruption as the whole CU would have to be isolated to accommodate the circuit identification process. It may well be that an electrician carrying out a risk assessment would decide that was reasonable in the circumstances (unoccupied house). However, tone generator signals could be applied to the wrong circuit and the tone receiver could pick up a signal at the point of work that was interpreted by the user as a 'clear indication' that the circuit was identified, when it was not. In the scenario depicted in this video, proving a change of condition at the terminal on the socket outlet (proved live - MCB opened - proved not-live) is probably the most practical and reasonable way to identify and disconnect the circuit prior to isolation.

It's a retractable shroud as opposed to an extending probe so it's not so bad, but your point still stands about potentially not being able to see. Also potentially problematic if you're trying to probe a socket dangling in mid air... I do think it's better than non retractable shrouds though, fixed ones (or removable ones that haven't been removed) are more likely to give you a false connection.

I don't think this is specific to martindale, but is more an issue with "2 pole testers" in general. They will only pick up when there is a voltage between two conductors, they won't pick up when *everything* is live or floating. For this reason and others I would be very careful about working on stuff that is "already dead" when you arrive. It is much better if you can confirm something is live, then isolate it and finally confirm it is dead. Even then it's not 100% foolproof, multiple feeds, borrowed neutrals and so-on are far from unheard of.

Here’s a scenario, you mention multiple sparks working on one site from the same consumer unit and, other trades working on site. So you’ve just isolated the breaker you’re working from. What happens if another of the aforementioned sparks, or worse still another trade on site, makes a change to the wiring in the loft, which for what ever reason, becomes connected in to the ring you’re on. They go back and turn on their breaker and you then get a shock. Surely the safest option in the instance where other trades are working, where possible, should be to lock off at main breaker?

Not an unusual scenario on a large commercial or industrial installation with lots of work going on at the same time. Management of safety then includes as part of any risk assessment before work starts a specific action to confirm whether other work is taking place that could affect your safety (or your work could affect theirs). Some large sites may operate a Permit-For-Work system to manage this too. Your scenario refers to a domestic house so the risk is probably higher as it's unlikely a safe system of work is written down to cover what's going on. Head on a swivel and always treat wiring as live until proven otherwise.

From what I've read on various comments to similar videos, the practice varies between DNOs (or DSOs as they are now?), which is not helpful. There should be no doubt that the service termination apparatus, including the fused cut-out is the property of the DNO, is therefore a component of the LV network and, as such, is subject to the DNOs Safety Rules applicable to that network. The DNO I used to work for has a specific switching authorisation for the withdrawal/replacement of cut-out fuses so the removal of a cut-out seal and then the fuse-holder _could_ be construed as unlawful interference. Only way to get a definitive answer is if it ends up in a court of law. Best not to go there.

I like your video and the process of proving dead was well demonstrated but would be good to identify where the process comes from. It is a legal requirement in the electricity at work regs 1989, it states when working on equipment it must be isolated from all sources of supply. In the definitions it states that an isolation is a disconnection from all sources of supply in such a way the disconnection is secured, I.e. disconnect the source and lock it to secure it. Also the process comes from the HSG 85 which is the HSE guidance for electrical safety. You also mentioned that a light on the proving unit identifies high voltage, high voltage in the EaWRegs is voltage over 1000V ac or 1500V dc between phase conductors and above 600V ac 900V Dc between phase and neutral, voltage range between phases. national grid introduced Medium voltage bet is not recognised in law but is in their own safety rules. Good vid though for house bashers, just a shame so many so called skilled electricians don't even know the safe isolation procedure.

It’s a legal requirement to work safely, ie isolated, yet the DNOs still resist us being allowed to pull main fuses, or make us jump through hoops to enable us to do so. It’s madness.

Hi Stuart, good to see such a correct and informed reply. There are many concerns with KZbin electrical videos, even from Artisan, but at least they are trying to improve things. Working at height is a major danger and even a non fatal shock can cause a reaction fall. Noticed this problem in an Artisan recent post. Another concern is understanding the role of an electrician when making changes to an installation and installing new work without detail drawings from a professional engineer. They then assume the role of designer and need a high level of knowledge of the full installation plus professional indemnity insurance. Anyway thank you Artisan for excellent videos and welcoming debate.

@@chrisrogers2848 how does the DNO (who owns and operates the service termination apparatus) gauge the competency of someone that is intending to operate the cut-out fuse? They **_have_** to do this as they have a duty to establish and operate a safe system of work under the same health and safety legislation (s.2 HASAWA 1974) that requires you and I to work safely. Any DNO with a policy of allowing anybody to pull main fuses without first assessing their competency to do so safely would eventually be guaranteeing a visit to the dock in the local court for their Operations Manager.
@chrisrogers28483 жыл бұрын
@@protectiongeek surely then by the same token they should be required to provide a safe means of isolation that can be operated without need for them to assess competence, which in practice probably means an isolator switch. There was an ideal opportunity to do this with the smart meter rollout but it was missed. Failing all else, the process for getting them to isolate the supply needs to be much more accessible and convenient, otherwise people will always be tempted to just pull the fuse themselves on the quiet just to get the job done, which means no safety precautions at all.
@protectiongeek3 жыл бұрын
@@chrisrogers2848 the requirement for provision of a point of isolation by the DNO is not in doubt but there is no qualification of that requirement such that operation of the PoI should not require a person to be competent and appoint as such in writing. If there was, that would create a **retrospective** burden to fit two-pole isolators to all service terminations. Clearly, DNOs concur with your conclusion that the provision of an isolator is a sensible step (although the person operating it in the context of the work carried out by an electrician must still satisfy the requirements of Reg 16 of the Electricity at Work Regs 1989). All new builds (as far as I know) incorporate an isolator. Some DNOs charge for retro-fitting one to a legacy service termination and some don't. As with so many things, the issue is one of cost - a valid consideration within the ambit of what is deemed "reasonably practicable". An electrician at work pulling the fuse "on the quiet" is taking a significant risk. We both know this happens several times each working day. However, if that action is material to the circumstances of an incident subsequently investigated and prosecuted by HSE etc, then a defence of "it was inconvenient to contact the DNO and wait for them to attend" is no defence at all. I know that the HSE take a particularly dim view of no isolation or things like sticking a bit of PVC tape over an MCB in the off position, given the availability of products like the Martindale kit demonstrated in this video.

The DNO I used to work for ensured that all operational staff with a live working authorisation had also to complete basic first aid training that included CPR and use of AED equipment. This was part of the safety case supplied by the DNO to the HSE to justify the issuing of live working authorisations to suitably trained and competent persons. That said, an AED won't do anything for a patient whose heart has stopped. I understand that the latest AED models, once the pads are properly applied to the patient's body, can determine whether the patient is suffering VF (in which case it will proceed with the defib sequence) or that the patient is asystole (in which case it will tell the AED operator the heart appears to have stopped so no shocking takes place).

Not so keen on the advert type videos. If the build quality was iffy or something, would you actually say? I'm sure you would but it does put slight doubt in my mind. Nagy does with his Bosch stuff. But I've never heard you once make any type of criticism, albeit, constructive criticism, of a piece of kit that you dedicate an episode to. Although I may have missed one if you did. Cory often asks for things to be added to EV charging points and it's cool when the manufacturer adds his suggestions in, but I assume you've paid for those as part of the job you're doing.

@protectiongeek3 жыл бұрын
Agreed. In this scenario, it was likely to have been reasonably practicable to have isolated the whole house supply in order to remove the "packaging" from the socket outlet to prepare it for testing. With the supply to the CU still on, it would have to be assumed that the wiring to the socket outlet was live and so removing the temporary protection applied by others was indeed live working that could not be justified in the context of the Electricity at Work Regulations. If the circuit was fed from a 12-way TP&N DB in a busy factory a risk assessment and method statement would probably suggest a different approach to attempt to identify the circuit and prove it not live before removing the tape. If all else fails the RAMS would probably fall back to the use of adequate PPE (gloves with rated insulation, full-face rated visor and FR coveralls and NO metal knives or tools) to protect the electrician until the terminals can be exposed to allow the approved testing procedure to be applied.

Sorry, but if you're passionate about working safely then you've shot yourself in the foot before you even get started... using an open bladed knife where not necessary when opening the box, moving a metal handled blade towards potentially live conductors that also haven't been isolated and have been left unsecured outside of enclosure... Cluttered working area... As for the quality padlock... seconds to open without a key by any number of means - the point is to prevent accidental energisation as preventing deliberate override is virtually impossible.
