Manitoba have started enforcing 2018 code since November, here is a list of stuff relevant to residential homes.
4-022 neutral wire required for all light switches.
6-200 Multi position meter socket up to maximum of 4 meters
8-104 maximum circuit loading, label requirement from 2-100(4) only needed when using table 13.
8-200 calculated load for single dwelling has been changed to wattage instead of the previous amperage, this is due to the fact some dwelling uses 240V (residential) and some uses 208V (commercial), which means if using 208V then higher amperage is required to achieve the same wattage rating, thus by changing over to wattage in the code, it will reflect the proper capacity of the service that is required.
Section 10 grounding and bonding, this section has been rearranged to separate out grounding and bonding as they are actually different.
10-210 replaced. Service grounding connection shall be accessible, therefore it is not allowed to be located inside the meter socket as that is locked by hydro
12-610 Termination of armored cable. Caution ACWU90 is not a TECK cable and require the use of anti-short, whereas TECK90 do not require anti-short. This is because TECK90 cable have another layer of insulation that wraps the individual conductors. A lot of contractor treat ACWU90 as aluminum TECK, but it is not TECK.
10-612 devices that comes with bonding terminal shall have bonding be provided. Like light switches that do not come with a bond screw do not need a bond wire, but some light switches do (mostly sensors), so those switches needs bond wire, even if you have a non-metallic box (pvc).
10-614 Use overcurrent device rating unless it is for service entry, which shall use conductor rating.
16-300 PoE limited power conductor
26-652 separate dedicated circuit for refrigerator receptacle shall only be required in a kitchen. A kitchen is defined as including stove, countertop and cabinet. Therefore other fridge like bar fridge or under counter fridge do not require dedicated circuit and can be circuited to any other circuit.
26-656 arc fault protection. Hydro’s interpretation for renovation with existing receptacles on non-arc fault circuit is that they will allow it to remain and the receptacle can be connected to the same circuit using 2 methods.
Method #1: Provide armored cable or EMT conduit from the existing plug that the circuit will be extended from, then connect to a AFCI receptacle. Any more receptacle after the AFCI receptacle can be wired normally with standard tamper plugs.
Method #2: Replace the existing receptacle where the circuit will be extended from, then wire normally with standard tamper plugs after that.
Note there is no need to touch any other existing circuit or plugs as there is no requirement to bring everything up to code, only the modified device.
26-656 Dead front arc fault device is only permitted for use in the city of Winnipeg, hydro does not allow this. And it is only allowed for existing panels that have no space for new AFCI breaker.
26-656, 26-707, 26-722 AFCI is not required for out building receptacles, such as posts, garage, fence.
26-708 Weatherproof covers for receptacles, extra duty rating is only required for wet location, not for damp location. That means your plug recessed within the soffit is within damp location and do not require extra duty covers.
26-724 Kitchen wall receptacles no longer required separate circuit. The receptacle is still needed in the kitchen but you can place it on any other circuit. Maximum is still 12 plugs on 1 circuit but that is no concern for us as we should not be loading it up that high anyway.
32-200 Smoke and Smoke/CO Combo alarms. Permitted on AFCI and/or GFCI circuit provided there is integral battery backup. Otherwise it has to be on a non AFCI/GFCI circuit. Heat detector required to tie into Smoke/CO alarms are not allowed to be on AFCI/GFCI circuit as the heat detector does not comes with battery backup. Wireless Smoke/CO alarms are not permitted for code compliance. They can be used as additional optional alarms, but not as a substitute to hardwired alarms.
62-132 Heating devices, electric baseboard heaters within 1.8m off the ground and 1.5m to water source shall be GFCI protected. That means if you going to put one in the washroom, it needs GFCI.
64-218 Photovoltaic rapid shut down requirement is back in again. It is required at the utility meter and/or at the array
68-306 massage tub, the GFCI disconnect shall be visible from the tub.
For dwelling units that is more than 2 units. VDB permit is required for voice, data and video wiring. Cost is $20.25 per unit, or $360 fine. So this applies to fourplex and row house, not for single or duplex.
Building fee and charges updated for 2019.
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.

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.

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.
2019 Public Service Announcement
It appears there are 3 types of smoke alarms sold in stores, those are ionization, photoelectric and combination alarm types, ensure you will only install photoelectric type and NOT ionization and combination type. Ionization type are best to detect flash fires, as those tends to throw ionization particles in the air due to the extreme heat, however most home fires are of the smoldering type, which is better suited for photoelectric type detection. The combination type uses 2 different gate logic, with the OR logic, it combines the useful photoelectric with the annoying ionization which are prone to nuisance detection and causes many people to disable the alarm, and with the AND logic, it requires both detection to activate in order for the alarm to sound, which is too late.
