message: A fine picture, but do we need it twice in one article? And shouldn't the  article indicate that panelboards usually have a cover (even in the UK, I assume). --Wtshymanski 03:33, 18 January 2006 (UTC)
replies: text: You got a pic (under a suitable license of course) of a board with the cover on, maybe we could use that as the initial picture. the reason for the duplication is i wanted pictures asside detailed descriptions (which were way too long for an image caption) but i still wanted to have a picture in the standard initial picture position.

thread_title:  Duplicate picture 

message: While I think this is the most likely "internationally" understandable name, I suggest adding "electrical" to it, so it's more obvious on looking at the title what it is, since it's probably not immediately understandable to someone who isn't familiar with this turn of phrase. 68.39.174.238 08:41, 20 March 2006 (UTC)

thread_title:  Pics 

message: The article is much appreciated. A discussion of sub-panels common in today's construction would be appreciated by me. Especially the limitations on them. For example is it legit to add a 200 amp sub-panel(s) with its own main breaker by attaching the new sub-panel to the entrance lug on an existing main panel?Fried! 03:31, 29 September 2006 (UTC)
replies: text: I'm no electrician, but I don't think that's legit. I'm reasonably sure that (at least in residential setups), there has to be a single "MAIN" breaker that will cut off all power service. 68.39.174.238 21:12, 9 December 2006 (UTC)
replies: text:  NO!!!!!!!! That is downright scary.  Anyways... a 200A sub-panel? Are you feeding an entire separate house, like your neighbor?  The next device after the meter has to be the main breaker (even if there is a separate service disconnect near the meter.)  If your existing load center is 200A then your service entrance cable and meter are probably rated for that also. Your power utility would have to install new service entrance cable and meter if you need another 200A of service. HOWEVER, you could easily (and safely) add <50A sub-panel fed from your existing main load center by replacing four single space / single circuit breakers with two single space / two circuit breakers, making room for a 50A two space breaker for your sub-panel. BTW, what is it you need 200A for??? 50A should be plenty for a workshop or garage, even a large addition. JAK83 06:07, 5 February 2007 (UTC)
thread_title:  sub-panels? 

message: It would be interesting to note how much the amp rating of main breakers has risen over the years, like in the 1920s a U.S. house may have had a 50A or 75A main breaker, and today new homes are built with 150A, 200A, and 250A main breakers, just to keep up with the demand for electric stuff.
I noticed while I was in Japan, their household electric is a split-phase system like the U.S., 100V phase-to-N and 200V phase-to-phase, however, it is not uncommon for a Japanese home to have a main breaker of only 30A. JAK83 06:18, 5 February 2007 (UTC)
thread_title:  Electricity Demand 

message: I need to add a 50-amp circuit, but there is no romm in my service panel(only a single space left). Can I have a subpanel connected to the main service panel to house the 50-amp breaker or do I have to have a larger main service panel box installed?68.111.179.103 01:10, 23 April 2007 (UTC)
replies: text: I'd suggest you contact a local electrician (preferablly several) in whatever judristriction it is you live in. Regulations on this sort of thing tend to vary quite a bit arround the world. Plugwash 14:04, 23 April 2007 (UTC)

text: Second the above comment: We have no idea where you are or what the local rules are. 68.39.174.238 15:21, 14 July 2007 (UTC)

text: Third the above comment. Electricity can be a tricky beast. Often, electrical code is even worse. If you would allow me to make this loud, plain and crystal clear on this little island within this great forum...if you don't absolutely know every discrete and minute detail of what you're doing, please PLEase PLEASE STAY THE HELL OUT OF YOUR FUCKING PANELS! I'M NOT KIDDING HERE!! If you don't have the brains or spare change to hire a real expert to do this sort of work, it's my opinion that there's a good chance you're not smart or safe enough to do or even need what you think needs to be done.(64.50.228.36 03:04, 6 September 2007 (UTC)
replies: text:  Just to answer the question, no you can't, because you need a breaker on the feed to the subpanel!  The best thing to do is to remove three single-pole breakers from the main panel, install your (presumably two-pole) 50-amp circuit and another two-pole 50A breaker for the subpanel, and relocate the three removed breakers to the subpanel.  (Adjust the numbers appropriately if you need three phases.)  Hopefully it's obvious that anyone not aware of this important safety rule probably shouldn't be installing their own mains wiring.  71.41.210.146 (talk) 17:16, 26 January 2008 (UTC)
thread_title:  Subpanel? 

message: I wonder if the phrasing "For 480Y/277 volts (always three-phase)" is misinformative. While I agree that 480Y/277 is by far the most common occurance of 480 volts phase to phase, I have heard through second-hand sources that 480/240 single phase systems do in fact exist and that utilites will connect them. Unusual, to be sure, but for the sake of completeness and accuracy this could be addressed. But not by me.(64.50.228.36 01:39, 6 September 2007 (UTC)
replies: text: 480Y/277 V will always be three-phase, as neither two- nor single phase is able to form a Y-configuration. BP OMowe (talk) 20:07, 19 September 2023 (UTC)
thread_title:  Always is a strong word 

message: I don't know who this kid who sprayed a lot of this garbage on this topic was, but I'm scared to think that s/he is an electrician somewhere. Is it possible for articles that relate to this one major thing that everyone takes for granted, and that I know and love, to be joined under a wikiproject? Some of the stuff I've seen overall on the subject worries me. Experts please, preferably those who know just a bit more than white is neutral and bare/green is ground (earth for you "other" folks hahaw). (64.50.228.36 02:33, 6 September 2007 (UTC)
thread_title:  Wow 

message: Domestic CUs, which will be familiar to most readers, don't normally look like the current pic. Domestic CUs are almost always single horiztonal row, and the boxes are nowhere near as big as shown. Maybe someone has a pic that better represents most people's experience.
Tabby (talk) 03:06, 8 December 2007 (UTC)
replies: text: I have such a pic but I'd like to keep the three-phase pic alongside it, as this article is about both.  The section name "UK Fuseboxes (Consumer Units)" may be a problem though as it tends to indicate that only domestic CUs are the topic. Anihl (talk) 22:30, 17 December 2008 (UTC)
thread_title:  UK CU pic 

message: I'm not clear what value the categorisation "Modern CU with MCBs and an RCD / Older CU, usually containing no RCD" has - many early MCB installations were done with no RCDs.  I saw these regularly in the 1980s.  Does anyone think this is really useful? Anihl (talk) 22:30, 17 December 2008 (UTC)
replies: text: Making a few amendments to this section then, including renaming it so that the title allows for all types of board.  Amongst other changes, I'm deleting the separate section on Split CUs, which is not strictly accurate (a split busbar must still be supplied through the main incomer for the board - being RCD protected does NOT in itself make the section separately switched). Previously added some pictures of actual fuse boxes; I'll get some shots of Bakelite and modern CUs at the next opportunity. Anihl (talk) 03:01, 25 December 2008 (UTC)
thread_title:  UK Fuseboxes (Consumer Units) - categories - and stuff 

message: I have created a SVG that is Open Source that might be really nice for this page. I added a link at the bottom of the ARTICLE to the graphic in EXTERNAL LINKS so everyone can see it. 
The graphic is generic and I could modify it some for the Wiki if needed. 
It is also nice for mapping out ones circuits, or as a starting point for a more specific non-generic panel.

message: I find the table under Breaker Arrangement to be somewhat ambiguous. The phase labels for split phase are A, B, A, B. It seems as though it would be more accurate to label them something like A, -A, A, -A.  Kmuret (talk) 14:44, 12 January 2010 (UTC)
replies: text: I think L1 and L2 would be the correct way of denoting two legs of a split-phase service. A and -A would imply that a load connected between the two legs would yield 0V (A-A=0), where in fact it is (should be) twice the single-leg voltage.Noderaser (talk) 04:32, 15 June 2010 (UTC)
replies: text: L1, L2 and L3 are the three phases, so the correct denotation(?) would be L1A and L1B if the phase is split. BP OMowe (talk) 20:10, 19 September 2023 (UTC)

I changed the redirect to point to control panel (engineering) instead.

thread_title:  External links modified 

message: The section here is quite long compared to that article, and it's not clear how a 'consumer unit' is anything other than the British term for what we in the US call a 'breaker box'.  The section and the dedicated article are closer to a fork than a summary and full article.  But neither fully achieves its purpose, so their information should be consolidated by someone who understands what they're each saying.  — ˈzɪzɨvə (talk) 02:13, 12 January 2023 (UTC)
replies: text: If anything, I'd say the North American section should be broken out into an article of its own, and the UK section merged into consumer panel or vice versa. The reason is that when the EU boxes are added which neither use split phase nor ring circuits, we'll have an article that is way too long. If there are any other systems used in other parts of the world that can be added, this will be even worse of a problem, especially with the amount of pictures used. BP OMowe (talk) 20:33, 19 September 2023 (UTC)
replies: text: Support merge as proposed. There isn't enough material here for more than one article, and if more is added in the distant future (noting the larger article has actually shrunk since 2014), then content can be split to create a US-specific article.

thread_title:  Merging [[Consumer unit]] into here 

message: *There are units with Main Breakers, as mentioned in this excerpt
**"and the two hot wires are attached to the main breaker. Below the main breaker are the two bus bars carrying the current between the main breaker and the two columns of branch circuit breakers, with each respective circuit's red and black hot wires leading off."
*However there are also Main Lug Only (Sometimes also written as Main Lugs Only) Panels Available as well
*These must use a fuse/switch/breaker elsewhere, but nonetheless may be worth a mention?
*I just stumbled upon this in class today, so i am definitely not an expert, but here is a basic link i grabbed i guess (it also has as of right now one snapshot in the Wayback Machine too, so that is nice i'd imagine) :
** https://conquerallelectrical.ca/main-breaker-vs-main-lug/
*Anyways i hope i'll get around to adding this (assuming more experienced/knowledgeable people agree it is a worthy addition), or at least that this helps others looking into similar things.  Either way i'll keep you posted.
