Nekajui, a Ritz‑Carlton Reserve in Costa Rica (2025)

In early 2025, our team partnered with the construction team ofNekajui, a Ritz‑Carlton Reserve—Costa Rica’s first Ritz‑Carlton Reserve, located on the Peninsula Papagayo in Guanacaste Province. Nestled within a 1,400-acre private reserve with panoramic views of the Pacific Ocean, this luxury resort demanded excellence in every construction detail. For the electrical team, the project presented significant challenges: the resort’s remote coastal location, strict North American safety standards required for international luxury hospitality, and tight construction timelines combined to create four non-negotiable core pain points:

• Stringent Compliance and Certification Requirements: The project required UL-certified wiring to meet U.S. and Costa Rican electrical codes for high-end hospitality—a mandatory requirement for safety inspections and long-term operational reliability. Local suppliers were unable to provide complete UL certification for all required cable types, which would easily lead to project delays.
• Adaptability to Harsh Environments: Guanacaste Province has a tropical climate with year-round high humidity, salt spray, and occasional heavy rainfall. Ordinary cables would age quickly, resulting in high maintenance costs, safety hazards, and disruptions to guest experiences. The construction team needed cable products that could operate stably in humid, corrosive environments without compromising performance.
• Supply Chain and Inventory Reliability: With a scheduled opening date of February 2025 and a phased construction approach, the project required timely delivery of various cable types in precise specifications. Any shortages or delayed shipments would directly halt construction and delay the resort’s grand opening.
• Balance of Cost-Effectiveness: As a high-end resort, the budget prioritized quality, but the construction team still needed competitive pricing to control costs. They urgently sought a partner capable of balancing UL certification, durability, and affordability—a combination that was scarce among local suppliers.

The client’s needs were clear: find a reliable UL-certified cable manufacturer with experience in large-scale international projects, sufficient inventory, and customized solutions for tropical coastal hotel construction. This is exactly where our core strengths lie.

1. Precise Matching of Products to Project Needs

Based on the electrical layout of Nekajui Hotel, covering guest rooms, luxury villas, restaurants, spa facilities, and outdoor public areas, we tailored an exclusive cable solution. We selected four core cable types, each with unique performance advantages over similar products, and matched them with precise specifications to meet the various circuit needs of the resort:

1. 1 XHHW Cable (600V, 12 AWG–4/0 AWG)

As a professionalXHHW electric cable manufacturer China, we chose XHHW Cable as the core product for the resort’s main power distribution and outdoor/wet area wiring. Unlike standard THHN cables (which use thermoplastic insulation), XHHW Cable features cross-linked polyethylene (XLPE) insulation, offering the following core advantages:

• Water and Corrosion Resistance: Can operate stably in 75℃ wet environments (compared to THHN cables, which only withstand 60℃ in wet conditions), able to resist high humidity and salt spray erosion in Guanacaste and avoid premature aging.
• Excellent High-Temperature Tolerance: Can withstand 90℃ in dry environments, making it ideal for the resort’s HVAC systems and high-power distribution panels.
• Complete UL 44 Certification: Fully compliant with North American safety standards, completely eliminating safety inspection risks.

The XHHW Cable we provided covers specifications from 12 AWG (for branch circuits) to 4/0 AWG (for main feeder lines), ensuring stable power supply across the entire 1,400-acre resort.

1. 2 UF-B Wire (14 AWG–10 AWG, 600V)

For underground wiring scenarios (such as landscape lighting, pool equipment, and outdoor villa circuits), we recommended UF-B Wire—a direct-burial cable with a moisture-resistant PVC jacket and solid copper conductors. Unlike standard NM cables, which cannot be directly buried, UF-B Wire is designed for direct soil contact, resisting root intrusion and soil moisture. It eliminates the need for expensive additional conduits, saving the client time and labor costs while ensuring long-term durability in the tropical soil environment.

1. 3 Type TC-ER Control Cable (18 AWG–12 AWG, 600V)

For the resort’s complex control systems (including HVAC, lighting, security, and guest room automation), we selected Type TC-ER Control Cable. This multi-conductor cable (2-12 conductors) is equipped with a UV-resistant and oil-resistant jacket, and has exposed run (ER) qualification, allowing direct installation on cable trays or wall surfaces without additional conduits. Compared to Type TC cables (which require conduits) and heavier, more expensive Type MC metal-clad cables, TC-ER Cable offers the following advantages:

• Flexibility and Cost Control: Easier to install in tight spaces (such as spa walls and villa attics), significantly reducing material and labor costs.
• Complete UL 1277 Certification: Complies with strict control circuit safety standards, which is crucial for the resort’s intelligent luxury systems.

The TC-ER Cable we provided covers specifications from 18 AWG (for low-voltage controls) to 12 AWG (for high-power control circuits), precisely matching the various needs of Nekajui Hotel’s intelligent hospitality infrastructure.

1. 4 THHN/THWN-2 Cable (14 AWG–8 AWG, 600V)

For indoor dry-area wiring (guest room outlets, lighting, and kitchen circuits), we selected THHN/THWN-2 Cable—the industry standard for commercial construction. Featuring a nylon-jacketed PVC insulation layer, it offers the following advantages:

• Compact Size: Smaller diameter than XHHW cables, suitable for installation in crowded wall cavities and electrical boxes.
• Cost-Effectiveness: More economical than XHHW cables for dry indoor scenarios, helping the client optimize the budget while ensuring safety.
• Dual Certification: THWN-2 qualification allows use in wet areas (such as bathroom circuits), enhancing product versatility.

2. Uncompromising Safety and Quality

Compared to other suppliers, our core advantage lies in our unremitting pursuit of certification, quality, and reliability—the core needs most valued by the client. The specific delivery guarantees are as follows:

2. 1 Complete UL Certification Portfolio

Every cable we provided—XHHW, UF-B, TC-ER, and THHN—comes with complete UL certification (UL 44, UL 493, UL 1277, UL 83), which means:

• Zero delays in safety inspections, completely solving the common certification bottleneck in international projects.
• Full compliance with both Costa Rican electrical regulations and North American hotel industry standards, providing double protection for compliance.
