I use these blocks from Sparkfun:
Solid State Relay - 40A (3-32V DC Input)
They have four screw terminals - two for 3VDC to control and two for 24V - 380V AC for the load. They have the CE certification.
I bolt them down inside a NEMA enclosure and use standard residential wiring techniques (buy a book or two!) to wire them to standard outlets, where I plug in the load.
The controller (Arduino etc.) is typically mounted in a small plastic box outside the NEMA enclosure with a terminal strip to attach sensors and so forth. It's powered by a wall wart.
This approach meets code and is perfectly safe. For level of competence needed - you should be capable of doing residential electrical wiring. That's a useful skill to learn.
