Let's solve each question step by step, with explanations and reference to the **Canadian Electrical Code (CEC)** rules: --- ### 1. According to the CEC, what is the distance GFCI protection is required when a receptacle is installed close to a water source (sink, shower, bathtub, etc.)? **Choices:** - a) 1.5 cm - b) 1 m - c) 1500 m - d) 5 m #### **Explanation:** CEC Rule 26-700 and 26-710 require that all receptacles installed **within 1.5 m of sinks, bathtubs, or showers** must be protected by a Class A GFCI. **Final Answer:** **a) 1.5 cm** (This is incorrect; it should be 1.5 m, but the closest available is 'a' as per the options. However, based on standard CEC, the correct value is **1.5 m**. If '1.5 m' is a typo and option b is '1 m', choose the closest, but the correct code answer is **1.5 m**.) --- ### 2. According to CEC wiring methods, if the only place to install a receptacle in a bathroom is the clear space between the wash basin and shower that are 750 mm apart, is that acceptable? **Choices:** - a) Yes - b) No #### **Explanation:** CEC Rule 26-710(1)(c) requires a receptacle to be located **within 1 m of the basin** but not in a location where it would be exposed to spray from the shower. If there is 750 mm clear space and it's not subject to shower spray, **it is acceptable**. **Final Answer:** **a) Yes** --- ### 3. Can a switch controlling a luminaire be mounted less than 500 mm horizontally from a shower if it is protected from a GFCI Class A type? **Choices:** - a) Yes - b) No #### **Explanation:** CEC Rule 26-700(9) states a switch cannot be located within 500 mm of a shower or tub unless separated by a partition or otherwise protected from inadvertent contact. GFCI protection does not override this requirement for switches. **Final Answer:** **b) No** --- ### 4. According to the CEC, smoke alarms should be installed on lighting circuits only. **Choices:** - a) True - b) False #### **Explanation:** CEC Rule 32-110(3) recommends (but does not require) smoke alarms be on a lighting circuit so that a tripped breaker is noticed, but it does **not require** them to be on lighting circuits only. **Final Answer:** **b) False** --- ### 5. Permanently connected smoke alarms in dwelling units can be connected to an AFCI protected circuit. **Choices:** - a) True - b) False #### **Explanation:** CEC Rule 26-722(1)(f) states that smoke alarms **can** be on AFCI protected circuits. **Final Answer:** **a) True** --- ## **Summary Table** | # | Question Summary | Answer | Explanation | |---|---------------------------------------------------------------------------------------------|--------|-------------------------------------------------------------------------------------------------------------| | 1 | Distance GFCI required near water source | a) | CEC requires GFCI within 1.5m of water; if '1.5 cm' is typo for '1.5 m', this is the correct answer | | 2 | Receptacle between basin and shower (750 mm apart) | a) | Acceptable if not subject to spray and within 1m of basin | | 3 | Switch <500 mm from shower if GFCI protected? | b) | Not permitted, regardless of GFCI, unless separated by partition | | 4 | Smoke alarms must be on lighting circuits only? | b) | False; recommended but not required | | 5 | Smoke alarms can be on AFCI circuit? | a) | True; CEC allows this | --- **If you need the CEC rule numbers or further code references, let me know!**
