4-wire service
une alimentation à 4 fils

By 'service', we should understand 'supply'.

As for '4-wire', here it is in essence referring to a 3-phase + neutral (or similar) system, where we are interested specifically in the notional 'poles', rather than the details of the actual conductors used themselves.

Whether referred to as 'fils' (which is my preference, based purely on my exposure to technical electrical engineering jargon in FR documents I work with) or some other term, the key point here is how best to translate 'service', which is an oddly EN-US usage, slightly unusual, and is vital to render correctly. My answer would have been quite incorrect if I had simply translated '4 fils' — and Asker, please do note that your parsing isn't helping here: it is of course not a 'wire service', but rather, a 'service' that consists of '4 wires'; in EN-GB, it would have been written '4-wire service', which immediately makes the meaning clearer.

Usually, these 4 wires would be the 3 phases + a neutral wire.

  -> Thanks, B!

neutral  mchd: déjà proposé par Florence !

  -> No, EN is my mother tongue, so I appreciate the full significance of the word 'service' here, which MUST be translated!

agree  Daryo: yes, makes no difference if these 4 "wires" are separate or bundled in one cable. The point is that you get all 3 phases at the supply point + the Neutral.

neutral  Tony M: But this is 'service', not 'wire'; and in this instance, it's less likely to be a cable than actually 4 separate wires.

disagree  Daryo: you are assuming something that is not said in the ST - all it says is "3 phases+N" + a 200A feed for the whole of the business unit is anyway most likely through 4 separate pretty thick "wires". // OTOH alimentation triphasé ...is OK

Généralités sur les circuits triphasé

11.1.1 Définition tensions triphasées

Un système de tension triphasée est un ensemble de trois tensions alternatives, de même valeur efficace, décalées l’une par rapport aux autres de 120°.

un système triphasé peut servir à produire du monophasé (bipolaire)

-- 230 V (entre un conducteur polaire et un conducteur neutre )
-- 400 V ( entre deux conducteurs polaires)

ou des circuits triphasés multipolaires :

-- tripolaire ( uniquement les 3 conducteurs polaires - phases - )
-- tétrapolaire ( 3 phases + neutre)

note : le conducteur de protection ne servant qu'à un rôle de protection et ne conduisant en service normal aucun courant, celui-ci est généralement négligé dans la théorie de l'électrotechnique même si sa pose est habituellement obligatoire.

11.1.2 Courants triphasés
Dans une installation électrique triphasée, il arrive que les courants eux n’aient ni la même valeur efficace, ni le même décalage, ni même une forme sinusoïdale (comme par exemple un courant à travers une lampe économique). Les formules développées dans ce fascicule ne sont toutefois valables que pour des courants de forme sinusoïdale.

agree  Tony M: 'installation' would not be correct here (overtranslation) — it's by no means the whole installation! But as I said, 'alimentation' is indeed the right term for a 'service' here. Same as 'utilities' = 'gas / water / electricity services' = 'supplies'

  -> You're right - it's only about the supply / l'alimentation. Thanks!
