British plug standard BS 1363-1: 2016 + A1: 2018

Release Date: 2019-11-05
Upgrade considerations:
I. Changes to the new version of the standard:
(1) The contents of Table 2 have been modified.
Selection of British plug fuse in Table 2:
The new standard BS 1363-1: 2016 + A1: 2018 on the relationship between the wiring and fuses of replaceable and non-replaceable plugs:
(SASO 2203: 2018 / MS 589-1: 2018 requires the same)
Plug wiring diameter (mm 2 ) Rated current (A) Fuse current (A)
0.5 3 3 (5) A)
0.75 6 7 (13) A)
0.75 B) 10 10 (13) A)
1 10 10 (13) A)
1.0 B) 13 13
1.25 13 13
1.5 13 13
Remarks:
A) For special appliances, fuses with higher currents in parentheses are allowed. Special electrical appliances refer to electrical appliances that exhibit high transient inrush current and similar characteristics when turned on or off. This special case is not suitable for portable sockets such as power strips.
B) To use this rated current, the cable length should not exceed 2 meters, and passed the relevant test corresponding to the rated current.
(2) Other major changes:
1. Increase the requirements for electric vehicle charging plugs;
2. Increase the requirements for plugs with electronic circuits;
3. Add a plug size for reference. This plug is suitable for floor sockets and sockets with waterproof function.
Second, the relevant new standard mandatory implementation time:
UK BS 1363-1: 2016 + A1: 2018: August 31, 2019;
Saudi Arabia SASO 2203: 2018: 2018 has replaced the old standard;
Malaysia MS 589-1: 2018: No official time to replace the old standard time;
The Singapore Standard has not been updated for the time being, or SS 145 part 1: 2010.
Q & A:
  1. 1. Q: Typical example of fuse matching changes: a 2400W toaster, rated voltage 240V, rated current 10A, non-removable plug, cable length less than 2m. In the product safety EN 60335 standard, a 0.75mm 2 square power cord can be used. According to BS 1363-1: 2016 + A1: 2018, a 10A fuse rating is required, right?
    A: Yes.
  2. 2. Q: How to understand the special appliance of Note A in Table 2 that allows the use of fuses with larger currents in brackets?
    A: Refers to electrical appliances that will have high transient surge current and similar characteristics when they are turned on or off, such as vacuum cleaners and agitators.
  3. 3. Q: BS 1363-1: 2016 + A1: 2018 Are the fuse requirements in Table 2 applicable to replaceable fuses?
    A: According to UK safety regulations, the maximum fuse rating limits in Table 2 apply to replaceable wire plugs.
  4. 4. Q: Is there a certified model on the market for the 7 A fuse with 0.75mm 2 wire diameter in the new standard table 2?
    A: yes
  5. 5. Q: Are the Singapore standard fuse requirements of the British plug the same?
    A: Different, the current SS 145 part 1: 2010 about the relationship between the wiring and fuse of the replaceable plug and non-replaceable plug:
    Plug wiring diameter (mm 2 ) Rated current (A) Fuse current (A)
    0.5 3 3 (5) A)
    0.75 6 5
    0.75 B) 10 10
    1 10 10
    1.25 13 13
    1.5 13 13
Remarks:
A) For special appliances, fuses with higher currents in parentheses are allowed. Special electrical appliances refer to electrical appliances with high transient inrush current and similar characteristics such as vacuum cleaners and agitators when turned on or off.
B) To use this rated current, the cable length should not exceed 2 meters, and passed the relevant test corresponding to the rated current.
