You should use wires and cables that are rated for outdoor use and can withstand moisture, temperature changes, UV rays, and corrosion. You should also use weatherproof boxes, conduits, connectors, and fittings to protect your wiring from water and dirt. Avoid using metal conduits or boxes that can rust or conduct electricity. Instead, opt for plastic or fiberglass options that are durable and non-conductive.
in my experience Electrical Panel for outside location should be IP65 or IP 66 ingress protection, If Location near Coastal area Panel fabrication should be Staineless steel to prevent it from corrosion, Use outdoor-rated electrical wires to protect against moisture, temperatures, and UV radiation.
When selecting materials for outdoor wiring, it's crucial to consider the specific environmental conditions they'll face. For instance, in coastal areas, the high salinity can accelerate corrosion, making materials like stainless steel or coated products more suitable. Additionally, UV-rated cable ties and insulating materials should be used to prevent degradation from sunlight exposure. The use of weatherproof materials not only ensures safety but also extends the lifespan of the electrical installation, reducing maintenance costs and downtime.
Environment that the wiring will be exposed to is critical when choosing the correct wire type to use. It is also important to know the application where the wiring will be placed. Factors such as repetitive movement bending etc as well as oil being present in the machine should be considered. The routing of the cables or wiring is also critical as poor routing could lead to frayed wires or broken wires from contact in pinch points. If the location of the wiring is in a warm and sunny environment then UV resistance must be considered.
For outdoor electrical wiring, choose weather-resistant materials like UF-B or THWN wires, SWA, LC and use conduit for protection. Check hazardous area classification. Place outlets and boxes in elevated positions to prevent water ingress, and install weatherproof covers. Plan routes that avoid moisture-prone areas, and employ ground fault circuit interrupters (GFCIs) for safety. Opt for outdoor-rated fixtures and ensure proper grounding. Shield wiring within conduits to protect against physical damage, and use surge protectors to prevent power spikes. Regularly inspect and maintain the system to prevent wear and corrosion. Adhere to local electrical codes and consult with a professional electrician for a safe and reliable design.

Proper sizing and spacing ensure that the system can handle the expected electrical load and reduce overheating risks. Additionally, routing of cables must protect against environmental damage and interference with other systems or structures. Manufacturer guidelines are crucial for the longevity and proper function of the components used.
Our countries & areas have different codes. One must know what Voltage & Hertz is the common there. A very hard part can be using 120VAC/60Hz items in a region that is normally 220VAC/50 Hz.
Adherence to the national standards are too important so that to achieve the best personal and equipment safeties. For example the correct wire sizes, standard Circuit protection devices and marking of correct caution, warning or instruction symbols. Moreover, the fire prevention protocol must be adhered to.
Codes and standards: They are like traffic signs on the roads, or rather, like the lights on the highways for drivers to use at night. The use of any code and standard is a legality that people should use to advance their goals in any field. At first glance, it may be very difficult to assign each element to a code (especially in design), but it is worth the sweetness of using it correctly. Clearing the way in any field using standards and codes is very heartening. The biggest result of using these tools is giving a sense of security and safety in that work.
The third step is to plan the layout and design of your outdoor wiring. You should sketch a diagram of your outdoor area and mark the locations of your power sources, outlets, switches, lights, and appliances. You should also measure the distances and heights of your wiring runs and calculate the voltage drop and load capacity of your circuits. You should aim to minimize the length and complexity of your wiring and avoid crossing over or under other utilities or structures.
