Voor warmteontwikkeling in koperkabel was ik benieuwd wat de weerstand voor diverse diameters was.
Gelukkig heeft de Nederlandse pagina Koperdraad: Gegevens – Wikipedia deze tabel (let op weerstand is per 100m!)¹

Security alarm provider Woonveilig/Egardia really needs to work on their notifications towards end-users: outages are too frequend and not communicationed on to their customers
Posted by jpluimers on 2025/12/01
This was no incident:
[Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on Twitter: “Als zowel @WoonVeilig als @Egardia op 2 verschillende systemen een systeemtest failure geven en de apps 500-errors weet je dat hun infrastructuur plat ligt. Al een paar uur geleden, dus heel benieuwd hoe snel ze hun engineers wakker kunnen bellen.”
One of the problem is that Egardia/Woonveilig sees their social media channels as a broadcast-only. You can for instance se this when searching doing a [Wayback/Archive] egardia – Twitter Search or [Wayback/Archive] woonveilig – Twitter Search: no answers from them.
There were similar incidents in the past which I did not document on Twitter, but this outage was so large I had to documented it. So I started the [Wayback/Archive] Thread by @jpluimers on Thread Reader App with these images:
