Talk:Mains electricity

message: It's idiosyncratic, at best, that the title of the article uses a regionalism that's unheard of by the great majority of the world's native English speakers. It really should have a more intuitive title, although with the numerous redirects that have been incorporated, most people should still be able to find it.
That being said...if you need that many redirects just so that people can still find an article despite its clunky title, that would be your tip-off that the title could use re-working, in the first place. ‎ User:2601:195:c100:f220:3daa:c769:ac63:12b9 06:04, 26 October 2018 (UTC)
replies: text: I note that the anonymous IP from the US does not suggest an alternative?  As all the alternatives I am aware of are simply regionalism from other countries I have a suspicion that there is a desire to change the title of this article written in British English to an Americanism?

replies: text: This article not only seems to have a regional British English title, it has a synonym in the Terminology section - "Electrical grid"- Wikipedia does not do synonyms so this looks like a case where duplicate articles should be merged and one name chosen. Per MOS:COMMONALITY a more descriptive title such as Electrical grid would be preferred over a regional colloquialism. Fountains of Bryn Mawr (talk) 17:49, 27 October 2018 (UTC)
replies: text:  This article is not about anything called an "electrical grid".  It's really a guide to wall socket voltages. --Wtshymanski (talk) 01:41, 30 October 2018 (UTC)
replies: text: Then it should be merged/redirected to AC power plugs and sockets, or merged into Electrical grid. Large sections of the article are redundant to Electrical grid (and not about outlets) including: Power systems, Voltage levels, History of voltage and frequency, Voltage regulation, Power quality. The article seems to be an indiscriminate collection more than a topic. Fountains of Bryn Mawr (talk) 13:06, 30 October 2018 (UTC)
replies: text: I suppose, but it seems to me that they are different enough.  AC power plugs and sockets is specifically about plugs and sockets, and only indirectly the voltage, and mostly not frequency.  I haven't though about Electrical grid, but it should be on the larger, national scale distribution system. This one is on the house level, including the history on how we got here, and from before the very large nationwide systems. More specifically, the voltage and frequency going into a house, but not how it got there. It might be that more could be done for each article, to keep them on topic.

thread_title: Naming issue: regionalism shouldn't be used for a title of a non-nationally localized article

message: In describing US industrial voltages, the article mentions:  but the common voltages listed here would still be found for lighting and portable equipment.  While this is certainly true for plug-in equipment, including lighting, as well as I know 277V is very common for permanently wired lighting in larger buildings. (That is, line to neutral in a 277/480 system.)  The 277/480 three-phase is also available for larger induction motor loads. For one, in larger buildings the lines from breaker panels to loads are longer, but also 277V is convenient for fluorescent lamp balances common in commercial building lighting. More recently, electronic fluorescent lamp ballasts will run from between 120V and 277V with no adjustment. Gah4 (talk) 10:29, 18 February 2021 (UTC)
thread_title:  '' but the common voltages listed here would still be found for lighting and portable equipment'' 

message: AFAIK - the normal US supply voltage is ~240v and it is thus very misleading to state it is ~120v. Within a domestic customer's building (eg a house) the common circuits - eg lighting, outlets, are wired only to 'one half' of the split-phase supply and thus operate at ~120v. However the incoming supply (for typical single residences etc) and up to the service panel (consumer unit) is centre tapped ~240v. The breakers for each circuit may connect to either 1 or 2 'line' busbars as appropriate for that circuit. So, ~240v is supplied and available for use as appropriate to need.
Consequently, most portable and/or low power appliances plus most lighting equipments are designed to operate at ~120v. Higher power/'installed' equipments are designed for the split phase ~240v.
This situation is directly comparable to the ~110v split phase arrangements used for construction equipment in the UK.  — Preceding unsigned comment added by 79.64.179.87 (talk) 20:33, 9 April 2021 (UTC)
