The reason this outlet is open was because my washing machine was connected directly to it. I was advised to close it up by the people who took my old washing machine away. However i dont think i can wait until my friend has time to look at this. I likely cant turn the power on on the outlet at all right now i assume, how can i make sure myself that i can safely turn the power back on? electricity varies wildly in countries, im from austria if that helps.
Edit: a friend of mine who does some electrician work as part of his job (building pools) corroborated several of your comments (the only exposed cable is the grounding one and he offered to cover it up further at a later point after i put some tape on it)
thank you all for your answers and putting me at ease
Is there a reason you need to turn the breaker on for that circuit? Is it connected to a circuit like your kitchen or something?
In my opinion, if you aren’t an electrician and can leave that circuit off until your friend or whoever can look at it, then just leave that circuit off. That is the safest approach.
Otherwise,so long as the wires are not touching and the black and blue wires are capped off and not touching bare metal, in theory you should be okay. Again, this is theoretical, it is possible that there may be something that I cannot see or think of that may cause a house fire by turning that circuit back on.
the bathroom switch is turned off, that socket is in the bathroom, they asked me to turn it off while they did their thing
