I'm looking into wiring an outdoor hot tub.
2.5mm SWA cable going to an IP56 junction box mounted externally, changing to 2.5mm flat twin for internal wiring going to an isolator switch before going on to a 32 amp RCBO in the consumer unit.
I'm looking for info on how to do the change over of cable types in external mounted junction box. The SWA will be side entry. Can I then run the the flat twin & earth out the back of the box to get it indoors, or has it got to go side entry too through a glands before going inside. If it can go out the back how do I maintain the IP integrity of the box. Do I fit the same type of glands I used for the SWA and channel out a hole big enough to accomodate the glands?
The same applies too the isalotor, which will be mounted externally. I want the twin flat earth to enter and leave via the back of the box. Again what sort of glands do I need?
