There's more than one set of conductors between you and the power
station. The final main inside your house is often called a "main"
(singular).

I've tried to discover an answer to your question via the OED.
No real success!

The use of the plural goes back hundreds of years originally with water
main(s).

main, n.1

8. A principal channel, duct, or conductor for conveying water,
sewage, gas, or (usually in plural) electricity. Cf. main adj.2 5a,
mainsborne adj. Also in plural: the public supply of water, (or
electricity, etc.) collectively. Also fig.

[snip many examples]

It's my understanding that, in the case of water, you normally have a
main water pipe running down the street (so that's "the main"), and
smaller pipes (not called mains) branching off this for each house.

At the end of the street, though, that main would connect to a larger
main; and some streets would have more than one main pipe. It would, in
my opinion, be normal to call this whole network of pipes "the mains"
(plural). Each individual pipe would be called a main (singular) except
for the branch pipes that are too small to be considered main pipes.

In practice, the topology of the complicated network supplying the city
would be known only to the water supply authority. The average water
user knows only that the water that comes from reservoir to house
arrives via some unknown network of main pipes, thus "the mains".

The same reasoning would apply to gas mains and electric mains. (But not
the telephone network, cable TV, etc. The designers of newer systems
dropped the old terminology.)

Heh. That reminds me - there's an English lady that lives on our street. Her response to
the problems we've been having with the village well was "why don't they just connect to
the mains?".

I'm wondering whether "mains" is an abbreviation of "main pipes".

Wikip:
https://en.wikipedia.org/wiki/Plumbing#History_2

Wooden pipes were used in London and elsewhere during the 16th and
17th centuries. The pipes were hollowed-out logs, which were tapered
at the end with a small hole in which the water would pass
through. The multiple pipes were then sealed together with hot
animal fat.

Perhaps such pipes were still thought of in the plural even when joined
and didn't become a single pipe.

In article <gbipds...@mid.individual.net>, wibble...@gmail.com

UK estate agent descriptions of homes for sale will often specify the

If the public water or gas supply is damaged the media might report

With gas, electricity, and water, the one "main" supples all the houses it passes.

With telephone and copper-based cable TV, each house has its own pair of wires or co-axial cable back to the exchange or the cable TV street distributor box. (This is why it can be so slow to get phone/internet connected in some new housing developments.)

Fibre can be 'either way' with passive optical networks using splitters along the run.

The city of Toronto calls the pipe to each house a "service line".
I say it's still a main, because there's only one for the whole house:
it's the pipes *within* the house that aren't.

Exactly.

We, of course, do not extend this usage of "main" to electricity.
We limit it to water and gas, which come in pipes.

All the answers are very interesting, where I appreciate the complexity
involved, in that it's not always clear whence word usage.

In my brain, to remember this, I'm leaning toward the initial answers which
indicate it's a "plural" of the delivery mechanism (pipes or wires).

We also have to seriously take into account the history that was provided,
where the trailing "s" seems to have been in use for quite some time.

As for regional differences, I only really know Republik of California
usage, where it seems, to me, "mains" is standard usage for electricity
(but I don't recall hearing it in use colloqually for water - but I don't
live in a city - I live OUTSIDE the city where I, personally, live on my
own well water).

More globally, while the more general Wikipedia is only as accurate as what
someone puts into it, the Wikipedia intimates that electricity in "Canada"
is also called "Mains".

<https://en.wikipedia.org/wiki/Mains_electricity>
"Mains electricity (as it is known in the UK and Canada;
US terms include grid power, wall power, and domestic power)
is the general-purpose alternating-current (AC) electric power
supply. It is the form of electrical power that is delivered to homes
and businesses, and it is the form of electrical power that consumers
use when they plug domestic appliances, televisions and electric
lamps into wall outlets."

But Wikipedia could easily be wrong or not specific, as, for example,
Toronto usage can be different.

Overall, it seems to have a long history as "mains", for reasons that may
have to do with the fact that the mains is a system for the plurality.

This usage seems a bit reminiscient of Ernie Wise's plays "what he
wrote". Is there a better way of expressing it, or is it just me?

I was hoping someone could reword the "More globally..." sentence without

Snipping is good, but if it removes the object under discussion it's gone
too far! Personally, I'd prefer it if folk made the Subject line
relevant, but that's a lost cause.
