Electrical Solutions for Hospitality

The hospitality load profile is spiky and unforgiving

Hotels, lodges, resorts and conference centres combine loads that few other buildings carry together. Commercial kitchens run high-current cooking and refrigeration equipment. Laundries add heaters and large motors. Guest rooms are individually small but numerous, and their air conditioning tends to come on within the same hour. Pool filtration, borehole and booster pumps, cold rooms, lifts and conference audio-visual systems sit on top of all of it. The result is a load that peaks sharply around check-in and dinner service and falls away overnight.

That shape has practical consequences. Boards sized on average demand will trip at peak. Kitchens and laundries deserve their own sub-main distribution and their own protection, because a fault on a fryer or washer circuit should never reach a guest floor. Motor loads draw six to eight times full-load current on direct-on-line starting, so pump, chiller and air handling starting arrangements need deliberate thought rather than the simplest available option.

Continuity is the guest experience

A guest notices an interruption immediately, in the lift, the lights, the key card reader and the water pressure. Most Kenyan hotels run a standby generator, and the value of that generator depends entirely on how quickly and cleanly the load transfers. Deciding which circuits are genuinely essential, and separating them so the set is not asked to carry the whole property, matters as much as the transfer panel itself.

Assemblies typically specified on hospitality projects include:

• Main and sub-main distribution boards with kitchens, laundry, guest floors and back of house on separate sub-mains
• ATS and MTS transfer panels so essential circuits reach the standby generator without somebody being woken to intervene
• Motor starter panels and VFD drives for pool filtration, boosted water, cold rooms and air handling plant
• APFC power-factor panels to correct the lagging power factor created by motors and refrigeration and avoid penalties on a commercial tariff
• Solar AC and DC combiner boards where a property has added photovoltaic generation to cut daytime running costs
• Final distribution boards for guest floors, arranged so one room can be isolated without taking out the corridor

Coast, bush and the enclosures they demand

Location shapes how a panel should be built as much as load does. Salt-laden air at Diani, Watamu and Mombasa attacks terminations, hinges and enclosure hardware. Camps far from town deal with fine dust and long distances from the nearest technician. Kitchen and plant rooms add heat, humidity and grease. Enclosure type, gland arrangement, ventilation and ingress protection should be chosen for the room the board will actually live in, not copied from a Nairobi office specification.

Remote properties also make maintenance access a design decision rather than an afterthought. Clear labelling, accessible terminations, spare ways and instrumentation that lets a duty engineer see what a circuit is doing all reduce the number of times somebody has to drive out to site.

Specifying and commissioning hotel switchgear

Hospitality projects are examined by insurers, lenders and licensing authorities as well as by the operator. Panels manufactured to IEC 61439-1 and IEC 61439-2, using KEBS-certified components and installed by EPRA-licensed contractors, stand up to that scrutiny. Panel Tech Systems builds to those standards, holds ISO 9001 and assembles around Schneider Electric, ABB, Siemens and Control Techniques components, with Commander C, Commander S and NE-200 drives where variable speed control is wanted.

Cost varies with the incoming supply rating, the number and rating of outgoing ways, the enclosure specification demanded by the environment, the switchgear brand chosen and whether transfer, power-factor or solar combiner equipment forms part of the package, so quotations follow a load schedule and a single-line diagram. Manufacturing is in Nairobi and field teams are dispatched from there for installation and commissioning across Kenya, Uganda, Tanzania, Rwanda and South Sudan.
