A 24V DC push-button switch, along with a main switch for 380V AC – is this acceptable?
Thread Content
As the title suggests, there are 10 push-button switches in the PLC cabinet (those with fuses). The main switch for them is an AC 400V 10A switch – can this be used? I’ve never seen this happen before; do I need to replace it? Thank you
If it has insurance, it can’t be used. To be honest, it’s best not to get involved unless you are an electrician. If you have any objections, it’s best to consult an electrical technician and raise those objections. For reference.
