I've just been tidying up the cabling behind my console display unit. In doing so, I've wired together some mains extension cables/ 2-way splitters. They're daisy-chained so that each console has its own pair of sockets, to avoid all their cables trailing all over the place. I've used 13A cable, there is a total of only 8 sockets, and only one console will be on at any given time, so I'm not concerned about overloading the wiring. My only concern is that in order to daisy-chain them, I've connected two wires to each screw-terminal inside the 2-way splitters. They are firmly connected and there's no way they're coming out. However, because the wire is 13A it's quite rigid. This has resulted in some cases in the wires separating as they exit the terminal. They are firmly connected within the terminal however. Here's a picture to illustrate: The insulation has been stripped back that far because it was the only way I could get the wires to fit. With the insulation running right up to the opening of the terminal, the wires were too wide to get close enough to each other to both fit in the terminal. Once inside the terminal, they are firmly attached and not going anywhere. There's no possibility of the L/N/E wires shorting against each other, so I think this is safe. I just want to check whether there's any possibility of arcing between these connections since they are actually connected firmly to each other within the terminal itself. Thanks in advance!
