Whether it's a new build or a refurbishment, contour refurbishment is a major design project in a restaurant. If construction is not in place, it will directly affect business after opening. As a boss, if you don't want to turn off fire halfway through your meal, you should take it seriously.
When wiring power cord, cross-sectional area of the wire used must be suitable for maximum output power of electrical equipment. In general, for lighting 1.5 sq.m, for air conditioners and sockets 2.5 sq.m, for cabinets 4.0 sq.m, for input lines 10.0 sq.m.
Common wires are 2.5kv, 4kv. and 6 sq. Common wires such as switches use 2.5 sq. sq., and powerful electrical appliances choose copper wires 4-6 sq.
Laying hidden lines must be equipped with non-combustible PVC pipes. SG20 tubes are used for sockets and SG16 tubes are used for lighting. If piping is longer than 15 mm or there are two right angle bends, a cable box must be added. Luminaires on ceiling are attached using pull boxes.
To successfully pass fire inspection and acceptance, parallel distance between wires in kitchen and heating, hot water and gas pipes must be at least 300 mm, and crossing distance must be at least 100 mm.
Choose 10A for normal electrical sockets and 16A for high power appliances. Restaurant kitchens produce a lot of fumes and outlet panel is often most vulnerable spot. You can add a protective cover. It can not only isolate oil vapors, but also protect electrical plugs.
The problem with cliches is quality. If quality of outlet is not up to standard, a short circuit, an open circuit, or even a fire may occur. I hope everyone who is boss can pay attention to this.
When choosing a socket, first of all pay attention to surface layer. As a rule, most commonly used engineering plastic for PC. Its main feature is that it can be flame retardant and prevent fire. Look at rear seat design on back of socket. When placed in a wire box, smaller volume, more space it leaves for surrounding wires. The larger gap between wires, better heat dissipation, and relatively speaking, higher safety factor.
There is a slight misunderstanding here: method of selecting sockets by weight is unreliable. Even for outlets of same weight, some are heavier for steel sheet and some are heavier for copper sheet. And only those to which production process does not reach often use steel plates on back of socket.
I hope above content can really help you. Again, main power supply conversion costs do not need to be saved!
