Can metal electrical panels have a non-rectangular or squared shape?
In many countries electricity distribution boxes need a type certification. Other boxes are illegal. Type certification can be made only in an authorized laboratory. And the manufacturer needs another certificate to be able legally sell type certified products. The manufacturing process is auditioned every year. This all costs time and money.
There are all kind of other markings such as CE, which in Europe is manufacturer's way to claim &quot;this product fulfills standards&quot;. I have kept in my hands from far east imported (=ordered from a webshop) CE marked equipment and their CE marks were not worth more than the ink they contained. There's a good reason to demand actual certificates.
Actual certificates are traceable, authorities keep lists of certified products and what is manufacturer's certification status - does he still have a right to sell that certified product.
I guess nobody hasn't wanted to spend the time and money that type certification needs for obscure products such as lung or liver shaped electricity distribution boxes. A multi-billion dollar information campaign maybe could change the situation by successfully guiding a remarkable amount of people to want non-rectangular electricity distribution boxes.
Think about famous film stars, popular musicians and good looking celebrating sporty young people dancing and presenting their new liver shaped distribution boxes as their most valuable thing for the good living. Coca Cola has done it with their product - why not anyone else?
