A run of raceway between outlets or drawn-in points shall not have more than the equivalent of four 90 degree bends, including the bends located at an outlet or fitting.
This rule ensures that pulling conductors is feasible without excessive friction, damage to insulation, or risk of kinking. The "equivalent of four 90° bends" means a total of 360° of bends (e.g., four 90° elbows, or combinations like two 90° + four 45° that sum to ≤360°). If exceeded, additional pull boxes, junction boxes, or drawn-in points are required.
The question specifies "cable tube segment" (likely conduit/tubing), "including bends at the outlet or fitting," and "insulated conductor is intended to be introduced" (drawn in), which directly matches Rule 12-940's wording and intent.yt:video:Q4ioTVtq8GkQ4ioTVtq8GkUCJWtu2CoYBNLDih7hr6oM6w#motivation #industrialelectrician #electricalengineering X-Sense — Praised for affordabilityOne Million Kilometers https://www.youtube.com/channel/UCJWtu2CoYBNLDih7hr6oM6w2026-07-31T09:15:08+00:002026-10-01T15:51:34+00:00#motivation #industrialelectrician #electricalengineering X-Sense — Praised for affordabilityX-Sense — Praised for affordability, digital displays, and performance in independent tests.yt:video:38TGEnwx44438TGEnwx444UCJWtu2CoYBNLDih7hr6oM6wWhere should the harness be tied when using a man lift AWP (AerialWork Platform)?One Million Kilometers https://www.youtube.com/channel/UCJWtu2CoYBNLDih7hr6oM6w2026-06-01T14:45:00+00:002026-10-29T12:25:27+00:00Where should the harness be tied when using a man lift AWP (AerialWork Platform)?Where should the
harness be tied when using a man lift AWP (Aerial
Work Platform)? On the cross brace (as marked on the AWP)
Answer: ✅ The harness should be tied to the designated anchor point on the AWP/man lift, usually the manufacturer-provided tie-off point on the platform or boom.
Explanation:
Always use the approved anchor point provided by the AWP manufacturer.
Never tie to guardrails, controls, or any part not rated for fall protection.
This ensures the harness will support your weight safely in case of a fall and complies with OSHA/CSA fall protection standards.

number of conductors allowed in a conduit or plastic pipe according to Rule ?
Code Basis
Rule 12‑910 (CEC, CSA C22.1): Governs the number of conductors in conduits and tubing.
Primary criterion: The total cross-sectional area of the conductors cannot exceed the percentage fill limits in Table 8:
1 conductor → 53% fill
2 conductors → 31% fill
3 or more → 40% fill
Tables 6A–6K: Provide pre-calculated maximum numbers of same-size conductors in standard conduit or tubing sizes.
Designed for quick reference in installation or exams.
For small conductors (#14, #12 AWG), the table caps at 200 conductors, even in the largest trade sizes (like 6-inch EMT or equivalent).yt:video:rFOgS64fpUQrFOgS64fpUQUCJWtu2CoYBNLDih7hr6oM6wStep-down transformerOne Million Kilometers https://www.youtube.com/channel/UCJWtu2CoYBNLDih7hr6oM6w2026-04-01T12:30:53+00:002026-09-27T15:29:00+00:00Step-down transformerstep-down transformer.yt:video:G0Aj-XiMG04G0Aj-XiMG04UCJWtu2CoYBNLDih7hr6oM6wCEC Transformer Secondary Conductor Sizing, Transformer Secondary Ampacity 125 Percent RuleOne Million Kilometers https://www.youtube.com/channel/UCJWtu2CoYBNLDih7hr6oM6w2026-03-31T14:00:25+00:002026-10-03T07:20:37+00:00CEC Transformer Secondary Conductor Sizing, Transformer Secondary Ampacity 125 Percent Rulecec rule 26-256 transformer secondary conductor sizing 125%, canadian electrical code transformer secondary ampacity 125 percent rule, cec transformer secondary conductors 125% rated current requirement, how to size transformer secondary conductors cec 26-258 125%, cec dry type transformer secondary ampacity 125% exception rule 26-256(3)yt:video:cO3-2OoTp68cO3-2OoTp68UCJWtu2CoYBNLDih7hr6oM6wwhat is the minimum ground conductor size he should choose according to electrical Code?One Million Kilometers https://www.youtube.com/channel/UCJWtu2CoYBNLDih7hr6oM6w2026-03-31T13:45:04+00:002026-09-30T02:29:26+00:00what is the minimum ground conductor size he should choose according to electrical Code?what is the minimum ground conductor size he should choose according to electrical Code?**The minimum size for a copper grounding conductor (grounding electrode conductor) in the **Canadian Electrical Code (CEC)**, as adopted in Ontario's **Ontario Electrical Safety Code (OESC)**, is **No. 6 AWG** (or #6 AWG copper).**
This applies when Master Zhang chooses copper material for the grounding conductor connecting the electrical system's grounded point (typically the neutral at the service equipment) to a grounding electrode (e.g., ground rods, plates, water pipe, or field-assembled electrode), assuming the current-carrying conductors (ungrounded/service conductors) meet code standards for ampacity and installation.
### Key CEC Rules (2021/2024 editions, consistent in OESC)
- **Rule 10-812(1) & (2) – Grounding Conductor Size for AC Systems and Service Equipment** (see Appendix B notes):
The grounding conductor connected to a grounding electrode (per Rule 10-700) shall be sized **not smaller than No. 6 AWG copper** (or No. 4 AWG aluminum).
- For most common electrodes (e.g., manufactured rods/plates, field-assembled bare copper, or in-situ types like well casings), this is the **minimum** and often the **maximum required** size — the code states the conductor **need not be larger than #6 AWG copper** for solidly grounded systems, as most ground-fault current returns via the neutral/grounded conductor, not the electrode path.
- Exception: If connecting to a continuous metallic public water piping system (or similar interconnected electrodes providing low-impedance multiple paths), it may reference Table 17 (ampacity-based), but #6 Cu remains the practical floor in most building scenarios.
- **No upsizing required based on service size**: Unlike system bonding jumpers or equipment bonding conductors (sized per **Table 16** based on the largest ungrounded conductor ampacity or overcurrent device rating), the grounding electrode conductor to the earth electrode is capped/minimum at #6 Cu for typical installations. Even for large services (e.g., 400 A, 800 A, or higher), #6 copper is sufficient and commonly used to the electrode(s).
### Practical Examples (Ontario/Vaughan Common Practice)
- **100–200 A residential/commercial service** (e.g., #2/0 Cu service conductors): Grounding conductor to rods or water pipe = **#6 AWG copper** (bare or insulated).
- **400 A service** (e.g., parallel 250 kcmil Cu): Still **#6 AWG copper** to the electrode (though bonding jumper inside panel uses Table 16, e.g., #3 Cu).
- **Larger services** (e.g., 600–1200 A): **#6 AWG copper** remains the minimum (and maximum needed) to ground rods/plates — no need to match Table 16 sizes.
### Important Notes
- The conductor must be **copper or aluminum** (Rule 10-112); copper is preferred for direct burial or corrosive environments.
- It can be **bare** or **insulated** (Rule 10-116), continuous (no splices, Rule 10-806), and protected from damage.
- For field-assembled electrodes (bare copper buried), size per **Table 43** (often #6 min.), buried ≥600 mm.
- Always verify terminations (approved clamps/lugs) and local ESA inspector requirements (e.g., Bulletin 10-17-8 for water pipe or meter base cases).
- This differs from **bonding conductors** (e.g., to enclosures, equipment), which use Table 16 and can be larger (e.g., #3 or #2 Cu for bigger services).
Since the question specifies a "ground conductor" (grounding electrode conductor) made of copper, and the current-carrying conductors meet code, **#6 AWG copper** is the minimum Master Zhang should choose. For precise application on the project, reference the latest OESC (2024 edition) or consult an ESA-approved designer/inspector in Vaughan.
