Once you have a hole, get a decently sized bit (I find 1/4" works well here in both girth and length), put it into the hole you made, and carefully ream the hole out. The thinner knockouts will put up little resistance, but the main box won't let the bit ream it. A "knock out" or "KO" is a partially stamped opening in electrical enclosures that allows quick entry of a wire, cable or pipe via connector or fitting to the interior. With the right information and technique, you should be able to remove a "KO" from electrical panels and other electrical. A plastic electrical box —sometimes called a PVC junction box —comes with small, thin discs called knockouts. These are designed to be removed so wires can pass through.

According to Cambridge Dictionary, to splice means to “join the ends of something so that they become one piece. There are numerous use cases for fiber optic splicing.
For a standard single-phase residential connection on a serviced plot (terrain viabilisé), costs typically range from €400 to around €1,685 TTC — Enedis applies a 40% rebate (taux de réfaction) on the network-side portion of the work (source: Enedis barème PRO RAC 03E, April 2025). If your property does not currently have an electricity supply you will need to make application for such a supply to EDF (Edenis). The request for a supply is called a demande de raccordement, which can be made by letter or on-line at Demande de prestation liée au raccordement. (In a small number. Getting electricity in a new home in France requires three steps: an Enedis network connection (2–6 months, typically €400–€1,685 TTC), a CONSUEL compliance certificate (~€145 TTC), and an electricity supplier contract. 78 and. Metering boxes are divided into different tariffs: blue, yellow and green.
