==Canadian imperialism==
Is "Dief box" a common phrase other than in Canada? I could only find one reference with Google, and that was to a Canadian manufacturer of distribution boxes. --[[User:Wtshymanski|Wtshymanski]] 23:11, 4 May 2005 (UTC)
: Never heard it used in the UK [[User:Rob cowie|Rob cowie]] 20:51, 17 January 2006 (UTC)
== Duplicate picture ==
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). --[[User:Wtshymanski|Wtshymanski]] 03:33, 18 January 2006 (UTC)
Line 60 ⟶ 66:
::::I second this, with one small exception...As long as you don't violate wire bending space and radius as specified by the AHJ, and you abide by manufacturer's specs, you can do any damn thing you want with your panels. Top, bottom, backfeed, you name it. If you know what you're doing this should be a non-issue here (read-this comment thread should not exist) ([[User:64.50.228.36|64.50.228.36]] 03:04, 6 September 2007 (UTC))
Folks, I have been an electrical designer for nearly 20 years in industrial engineering with projects on 5 continents. Please take it from me, feeding a panelboard from the bottom is permissible and common -- in fact, most panelboard manfacturers design the interiors to rotate 180 degrees (invertible) within the enclosure to allow for top feed or bottom feed. Also, according to the IEC/NEC (NFPA 70), a main circuit breaker is not required anywhere unless a panelboard has more than 6 branch circuit breakers, which most do.
Now, here's what really throws people for a loop -- an otherwise normal branch circuit breaker may serve as a main circuit breaker (a.k.a. "back-fed") for a panelboard, energizing the bus bars and the branch circuit breakers. Of course, it must have sufficient current rating to serve as the main circuit breaker. 60 ampere and 100 ampere, 2-pole or 3-pole circuit breakers of the branch variety are often used as "main" circuit breakers in panelboards to avoid the expense of line lugs. Danger! Learn your stuff or hire an electrician to risk his life instead!
BTW, this article is full of misinformation and sloppy misuse of terminology, but I don't have anymore time to spend on it -- back to work. [[Special:Contributions/204.58.248.32|204.58.248.32]] ([[User talk:204.58.248.32|talk]]) 20:11, 1 April 2009 (UTC)
== Pics ==
Line 95 ⟶ 107:
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.([[User:64.50.228.36|64.50.228.36]] 01:39, 6 September 2007 (UTC))
:480Y/277 V will always be three-phase, as neither two- nor single phase is able to form a Y-configuration. [[User:BP OMowe|BP OMowe]] ([[User talk:BP OMowe|talk]]) 20:07, 19 September 2023 (UTC)
== Wow ==
Line 104 ⟶ 118:
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.
[[User:Tabby|Tabby]] ([[User talk:Tabby|talk]]) 03:06, 8 December 2007 (UTC)
: 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. [[User:Anihl|Anihl]] ([[User talk:Anihl|talk]]) 22:30, 17 December 2008 (UTC)
== UK Fuseboxes (Consumer Units) - categories - and stuff ==
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? [[User:Anihl|Anihl]] ([[User talk:Anihl|talk]]) 22:30, 17 December 2008 (UTC)
: 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.

== SVG Open Source Graphic ==
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.

== Two Phase or Split Phase? ==
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. [[User:Kmuret|Kmuret]] ([[User talk:Kmuret|talk]]) 14:44, 12 January 2010 (UTC)
: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.[[User:Noderaser|Noderaser]] ([[User talk:Noderaser|talk]]) 04:32, 15 June 2010 (UTC)
::L1, L2 and L3 are the three phases, so the correct denotation(?) would be L1A and L1B if the phase is split. [[User:BP OMowe|BP OMowe]] ([[User talk:BP OMowe|talk]]) 20:10, 19 September 2023 (UTC)
== panel board ==
The term "[[panel board]]" used to redirect to this [[distribution board]] article.
I changed the redirect to point to [[control panel (engineering)]] instead.
Have I made a horrible mistake?

== 19th June 2014 edit ==
Is the 19th June 2014 edit definitely an improvement? It's worded in the first person and is rather bias towards the outdated system - the "old and loved" colours, etc. [[Special:Contributions/92.28.252.70|92.28.252.70]] ([[User talk:92.28.252.70|talk]]) 23:12, 20 August 2014 (UTC)

== Merging [[Consumer unit]] into here ==
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 [[wp:content forking|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. [[User:Xyzzyva|— ˈzɪzɨvə]] ([[User talk:Xyzzyva|talk]]) 02:13, 12 January 2023 (UTC)
: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. [[User:BP OMowe|BP OMowe]] ([[User talk:BP OMowe|talk]]) 20:33, 19 September 2023 (UTC)
::'''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.

== Potential for Addition/Mention of "Main Lug(s) Only" Electrical Panels ==
*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.
