1. Enclosures, Cables and Connectors

2. Enclosures ● Needs to withstand hostile environments-rain, snow, saltwater blowing debris. ● Needs a full hinge and a positive latching system. ● Nema type 4 or 4X ● Materials available: ● ABS plasic ● Polycarbonate ● Fiberglass ● Stainless Steel ● Aluminum

3. ABS Plastic: Advantages and Disadvantages ● Light ● Easily modified by machine shop ● Nonconductive ● Brittle ● Not UV resistant – needs paint ● No Hinged Units

4. Polycarbonate: Advantages and Disadvantages ● Light ● Easily modified by machine shop ● Fairly durable ● More UV resistant than ABS plastic ● Nonconductive ● Black or clear color ● Still needs to be painted for UV resistance ● No Hinged Units

5. Fiberglass: Advantages and Disadvantages ● Lightest ● Easily modified by machine shop ● More durable than Polycarbonate ● Mostly UV resistant ● Nonconductive ● Best R factor ● Most inexpensive ● Pain to machine (dust) ● Will break down over long time (years) if not painted

6. Stainless Steel: Advantages and Disadvantages ● Most durable of all materials (will last forever) ● Pain to machine (hard material) ● Most heavy ● Conducts heat/cold/electricity ● Most expensive

7. Aluminum: Advantages and Disadvantages ● Very durable (will last forever) ● Easy to machine ● Expensive ● Heavy ● Conducts heat/cold/electricity ● Needs coating ● 2 nd most expensive
