I recently installed a cabler riser on my board and noticed that the wood above the cable riser is a tiny little bit hotter than the rest of my board. Also when the power is turned off.
I don’t really know what can be causing this, so I was curious if any other people had experienced the same?
Everything seems to be running fine (no smoke or anything).
Do you have a connector for the phase wires in there? They connectors may have more resistance and generate more heat. Otherwise, the insulation from the riser is holding in all the heat from the wires where as the exposed sections dissipate heat to the air around which gets blown away
Ahh, how did you do the 90 degree bend? If the wire is bent to much then compressed it may cause the strands to break, reducing the effective gauge at that one section which makes it hot
Could it be the cables are grouped tighter together there. Cable grouping factors are some thing that’s calculated in building industry as it’s heated from neighbouring cables and magnetic fields can increase heat as well as resistance in joints and connectors.
