I admit that Wylex isn't like it used to be, but I still prefer it to some other brands.

I'm still rather partial to the Crabtree C50 range for commercial work. Good solid engineering.

would the volts always be 230 or 415??

I am guessing it would be 230V
The voltage has to relate to the actual voltage on the primary or secondary of the transformer, so it depends upon the particular application.
