Still have to built it up. On my new setup. On my current setup, using multiplugs. Not very neat.
For new setup, I will have dedicated wire from DB board to tank.
Will be using normal wall mount electrical units.
First a stove switch. That switch off both Live and Neutral. Price around R135
4 Single wall plugs 12*8cm for timers for lights. About R36
4 Double wall plugs 12*12cm for about R52.
All mounted inside a fibreglass cabinet.
Total price R487, cheaper than a DB board. And I can switch and plug out everything normal.
