The type of plug used for the power cord

1. European Plug

(1) European Plug: Also known as the French standard plug or pipe plug.
Plugs have suppliers and specifications, such as: KE-006, YX-002, etc., and certifications from various countries: (D – Denmark, N – Norway, S – Sweden, VDE – Germany, FI – Finland, IMQ – Italy, KEMA – Netherlands, CEBEC – Belgium).
Tail: N/1225.

(2) Power Cord Identification with Code: H05VV□□F 3G 0.75mm²

• H: mm² identification
• 05: Indicates the voltage rating of the power cord (03 for 300V, 05 for 500V).
• VV: The "V" before the core insulation indicates the front insulation layer, and the second "V" represents the sheath insulation layer. For example, RR represents rubber insulation, and VV indicates PVC insulation; N represents neoprene.
• □□: The first "□" is a special code; the second "□" indicates a flat cable. For instance, adding H2 indicates a flat two-core wire.
• F: Indicates the cable is a flexible wire.
• 3: Indicates the number of internal cores.
• G: Indicates grounding.
• 0.75mm²: Indicates the cross-sectional area of the power cord.

(3) PVC: The material refers to the reinforced insulation layer with high-temperature resistance up to 80°C. Soft PVC has a hardness of 78° to 55°, and the higher the number, the harder the material. Rubber cables, for example, can withstand temperatures below 200°C.

2. English Insertion

(1) English Plug: 240V 50Hz with a withstand voltage of 3750V for 3 seconds, fuse ratings (3A, 5A, 10A, 13A) (FUSE) → Fuse. Size requirements: total length 25-26.2mm, middle diameter 4.7-6.3mm, metal cap diameter at both ends 6.25-6.5mm (silk screen BS1362).

(2) Internal Wiring of the Plug: (When disassembling the BS plug, the L wire (live) on the right connects to the fuse. The length of the ground wire must be greater than three times the length of the live wire and neutral wire. Loosen the fixing screw, and use external force to pull it out; the wire should eventually fall off. The screws fixing the three wires must be tapered.)

(3) Power Cord Identification: The identification for the power cord is the same as that of the European plug.

3. American Plugs

• (1) American Plug: 120V 50/60Hz, divided into two-core wire, three-core wire, polar and non-polar versions. The copper terminal in the American plug must have a plug terminal sheath.The wire printed on the two-core wire represents the live wire. The wire connected to the larger polarity plug pin is the neutral wire, and the wire connected to the smaller pin is the live wire (the concave surface of the power cord is zero, and the round surface of the wire is live).

(2) Wire Types:

• NISPT-2: Double-layer insulation; "NISPT" stands for double-layer insulation, and "-2" indicates two-core wire with insulation in both layers.
• XTV and SPT: Single-layer insulation. "-2" represents two-core wire (the wire body is grooved, and the outer layer is directly insulated with the copper core conductor).
• SPT-3: Single-layer insulation with a ground wire. "-3" represents three-core wire (the wire body is grooved, with the ground wire in the middle being double-layer insulated).
• SPT and NISPT are both offset wires, while SVT is round wire with double-layer insulation.

(3) American plugs typically use certification numbers, rather than directly displaying the UL symbol on the plug. For example: E233157, E236618, which are printed on the outer jacket of the wire.

(4) Differences Between American and European Plug Wires:

• European insertion is denoted by "H".
• The number of wires used in the US specification is as follows:
• 2×1.31mm² (16AWG)
• 2×0.824mm² (18AWG): VW-1 (or HPN) 60°C (or 105°C) 300V.
• 1.31 or 0.824mm²: Represents the cross-sectional area of the wire core in mm².
• 16AWG: Represents the wire's cross-sectional area in American Wire Gauge (AWG), which corresponds to the mm² value above.
• VW-1 or HPN: VW-1 represents PVC insulation; HPN represents neoprene.
• 60°C or 150°C: Indicates the temperature resistance of the power cord.
• 300V: Represents the withstand voltage strength of the power cord, different from the European standard (where 03 or 05 is used to indicate voltage strength).

4. Japanese Plug: PSE, JET

VFF 2×0.75mm² -F-
(1) VFF: V represents the wire material (PVC), and FF indicates a single-layer insulation with grooved wire.
(2) VCTFK: VC indicates PVC as the wire material; TFK represents a double-layer insulated wire with an offset conductor. The outer layer is a multi-layered PVC insulation around the copper core wire.
(3) VCTF: VC represents PVC as the wire material, and TF indicates double-layer insulation with round wire.
(4) There are two types of power cords:

• 3×0.75mm²: Three-core wire, with 0.75mm² representing the cross-sectional area of the core.
• 2×0.75mm²: Two-core wire, with the same cross-sectional area for each core.

(5) F: Indicates that the cable is made from a flexible material.
**(6) The Japanese plug three-core wire plug directly locks the wires (good safety performance and convenience).
