I got a new style wylex rcbo NHX
It has no load connected to it, only power.
When I press the Test button I can see an arc inside, from the side (dark room).
When in a CU you wouldn't normally see this.
Can anyone explain the reason. (I could understand it if there was a load) but I thought the test button wouldn't cause this.
Thanks.
