NEW 2018 CODE UPDATE
1. CEC 2018 to be released on Jan 2, with 262 revisions/clarifications from 2015.
2. 8-104 continuous current rating to be labeled on all electrical distribution equipment. Panels, switchboard, MCC, CDP, meter stacks, etc.
3. 26-242 transformers bigger than 50 KVA shall have minimum horizontal working space of 1m on the side of conductor termination. This applies to one side if the transformer have both the primary and secondary feeder connected to one side, or both side in the normal case.
4. Table 39, if used, shall have the calculated continuous current rating labelled on electrical distribution equipment. This is mostly used in residential.
5. Temperature rating applied to feeder sizes to Tables D8A-D11B, D17A-D17N, D12E (1) (2)
6. Section 4 light switch shall have identified (neutral) conductor in junction box. Previously for the dimmers that doesn’t require neutral, the bond is used as reference as code allows for minor leakage through bond, hence that’s how it gets power, but no longer.
7. Table 11 & 12, EV table D1 new conductor/feeder types. There seems to be at least 4 different types of charger cable.
8. Section 6-112(2) overhead service feeder point of attachment.
9. 6-212(3) utility service line side feeder not to touch or cross load side feeder.
10. 8-104(5)-(7), continuous operation 80% or 100%.
11. 8-106(1) 5% rule deleted.
12. 8-106(11)-(12) EV energy management systems (EVEMS) to apply reduced demand factor.
13. 8-110 determination of areas above/below ground, generalized.
14. Section 10 rewritten, table 16A & 16B consolidated into table 16.
15. Armored cable can now be used under slab.
16. Section 12 new technology cable PCS, NMDH90. Combined power and data in a single hybrid feeder.
17. 12-102(1)-(2) low temperature conductor, refer to appendix B notes.
18. 12-1302 deleted.
19. New rule regarding running of extra low voltage feeder on suspended ceiling (ACT).
20. 12-1250 to 12-1268 high density polyethylene (HDPE) conductor in conduit types.
21. Section 16 rule for power over Ethernet, refer to table 16.
22. 16-212(5) requirements for equipment class 2 output.
23. Section 18 intrinsically safe non-incentive circuits for zone 2, refer to appendix F and appendix J. updated for user friendly wording.
24. New table 70, equipment types permitted in different zones.
25. Heavy duty (HD) liquid tight flexible metal conduit now allowed for use in hazardous locations, zone 2.
26. 18-052 appendix B temperature outside ambient range.
27. Section 29 new table 69, hazardous locations within bulk storage space.
28. Section 24, C22.2 No. 204 line isolation monitoring alert trigger level increased. Can now use metallic conduit in zone.
29. 24-102 clarified.
30. Section 26 unit substation.
31. 26-258(4) primary and secondary conductor of high voltage and low voltage transformer.
32. 26-722(a) more than one refrigerator receptacle allowed per circuit.
33. 26-724 AFCI exemptions reduced or removed.
34. 26-724(e) no need for dedicated circuit in kitchen area.
35. 26-700(12) tamper receptacles required in hotel guest room, daycare, schools.
36. 30-200 combustible materials may be in proximity to light fixtures.
37. Section 30 disconnect to LED light fixture exceeding 150VAC to ground.
38. Section 32-200, 32-206.
39. 32-119 smoke/co alarm with battery backup are allowed to be on AFCI/GFCI circuit.
40. Section 62 electric heating in area with sink, shower or tub require GFCI protection.
41. Section 64 renewable energy systems, disconnect means, rapid shutdown system, define recombiner.
42. 64-202 feeder voltage exemption raised from 1000VDC to 1500VDC.
43. Section 78 GFCI expanded to floating piers and docking facilities.
March 2018 update, all new houses shall have minimum of 200A service. This is part of the EV charging requirement update but most only applies to commercial installations. This is the only part that affects home owners.
