Bang on design and use! ‘Forbidden reach around’ Tell people – just because it fits you should not plug it in. Did you know that figure 8 power cable plug (IEC 60320 type C plug also known as IEC C7) fits into XLR make connector? If it’s round outside, don’t plug an AC cord in, →
Very many electrical equipment and fluorescent lamps powered from 230V AC have a filtering capacitor on power input between live and neutral. This is typically there for interference suppressing. That capacitor is normally X rated “self healing” type, but they can sometimes fail. When they fail their case starts turning black, and they can start →
No audio signal. Only humming. This is how 6.3 mm plug and PowerCON meet. There are XLR and Speakon combo connectors designed for things like this. But this is PowerCON connector designed to carry mains power. Read more on PowerCON at https://www.epanorama.net/newepa/2018/10/01/powercon-connector/ Fortunately the 6.3 mm plug here only connects to the center ground pin. →

Germany and the EU have spiraled headfirst into the globe’s worst energy crisis since the Arab oil embargoes of the 1970s and 1980s. All across the continent, Europe’s energy policies have led to astronomical price increases, industry shutdowns, potential energy shortages, and geopolitical vulnerability. The European Union and its 27 member states have invested more →
I just saw this Facebook post in AC Disaster group and had to react to it! Source: Post by Jerry Hicks at AV Disasters Facebook group (used with permission) Almost clever! You can actually plug in US charger to speakon connector and have it to make contact with two “pins” (1- and 2-). You can →
In Greece the standard mains power voltage is 230 V and frequency is 50 Hz. The power plugs and sockets are of type C and type F. I also saw some Type L (Italian) power oulets at hotel This is a somewhat strange looking extension cord. Thetr are somewhat strange looking outlets on this permanently →
They are heavy (because of their iron core) and can be very large. The power transformers are design to operate best with an almost constant load which is equal to their rating. The maximum efficiency being designed to be at full load. Actually, all the transformers are the same that is same design formulae apply →
What is a drip loop? https://blog.solidsignal.com/tutorials/what-is-a-drip-loop/ The drip loop is a slack bit of cable that sits lower than the rest. The whole purpose is to let water pile up at the bottom and drip off. If your cables were tight, water from outside could travel down the wire and get straight into an outlet →
Russia tried to cut off electricity to about two million Ukrainians in a cyber operation scheduled to take place on Friday night, April 8th. The Russian state-sponsored hacking group known as Sandworm tried on Friday to take down a large Ukrainian energy provider by disconnecting its electrical substations with a new variant of the Industroyer →
