# Electrical Travel to Vancouver, Canada - New vs Questionable Source: https://www.youtube.com/watch?v=rg1xXCzLdQ0 Recap page: https://rapidrecap.app/video/rg1xXCzLdQ0 Generated: 2025-07-17T05:40:03.811+00:00 --- ## Quick Overview Electrical travel in Vancouver reveals a stark contrast between modern code-compliant installations and older, questionable wiring practices, with many public and older residential GFCI outlets found to be non-functional despite appearing to work, posing significant safety risks. **Key Points:** - The speaker successfully replaced a popping AFCI breaker in his bedroom, demonstrating the process and explaining that AFCI breakers trip at over 40 milliamps of ground fault. - Vancouver's residential power typically uses two 120V AC phases 180° out of phase, providing 240V AC, which the speaker considers safer than European 240V as accidental contact with a single live wire is only 120V to neutral. - An older apartment building showed widespread loose outlets and a complete lack of AFCI or GFCI protection in the kitchen and washrooms, despite the fire risk from arcing. - Multiple public GFCI outlets in community centers and outdoor areas were found to be non-functional, failing to trip even at 30+ milliamps of ground fault, despite their test buttons appearing to work. - A 35-year-old house under renovation lacked GFCI protection in the kitchen and by sinks, though a shared GFCI for washrooms was functional, highlighting outdated safety standards. - Apartment buildings in Vancouver receive three phases, with individual apartments getting two 120V phases 120° out of phase, resulting in around 205V AC, making appliances run about 25% weaker than in houses. - Connecting a scope's earth to neutral on an AFCI circuit caused it to trip due to a voltage drop between neutral and earth, creating a current imbalance exceeding 40 milliamps. **Context:** The video documents an electrical enthusiast's observations and experiences with electrical systems in Vancouver, Canada, spanning his own home, an older apartment where his mother-in-law lives, public community centers, and a newly acquired 35-year-old house undergoing renovation. The speaker provides practical demonstrations, such as replacing an AFCI breaker, and conducts tests on various outlets to assess compliance with modern electrical codes, particularly regarding Arc Fault Circuit Interrupters (AFCI) and Ground Fault Circuit Interrupters (GFCI) for safety. ## Detailed Analysis The video provides a detailed exploration of electrical systems in Vancouver, contrasting modern code requirements with older installations and highlighting significant safety concerns. The speaker begins by demonstrating the replacement of a faulty AFCI breaker in his own home, explaining its function and the North American 240V system derived from two 120V phases. He then examines an older apartment, revealing widespread loose outlets and a complete absence of AFCI or GFCI protection, which he identifies as a fire hazard. His tests on public GFCI outlets in community centers expose a critical issue: many are non-functional, failing to trip even at high ground fault currents, despite their built-in test buttons appearing to work. This raises serious questions about public safety monitoring. The speaker also assesses a 35-year-old house under renovation, noting the lack of GFCI protection in key areas like the kitchen and by sinks, indicating outdated code compliance. He explains that large apartment buildings receive three phases, with individual units getting 205V AC from two 120V phases that are 120° out of phase, leading to weaker appliance performance compared to houses. Throughout the video, the speaker emphasizes the importance of AFCI and GFCI for preventing fires and electrocution, demonstrating how even a small voltage difference between neutral and earth can trip an AFCI. ### Home Electrical System & AFCI Replacement - Speaker's breaker panel setup includes AFCI for bedrooms and washrooms - He replaces a popping AFCI breaker in his room - He explains the 120V/240V North American system and its safety compared to European 240V. ### Understanding AFCI & GFCI - AFCI trips at over 40 milliamps of ground fault - GFCI is mandatory in washrooms and outdoor outlets - Speaker demonstrates GFCI testing with a dedicated tester. ### Vancouver's Power Distribution - Three-phase 10-11kV power is distributed to transformers - Transformers create two 120V phases 180° out of phase for 240V in houses - Apartment buildings receive three phases, with apartments getting two 120V phases 120° out of phase for approximately 205V AC. ### Electrical Safety in Older Apartments - Speaker observes extremely loose outlets in an older apartment - He finds a complete lack of AFCI or centralized GFCI protection in the apartment - He identifies a risk of arcing, heating, and fire from loose connections with high current loads. ### Public GFCI Outlet Malfunctions - Speaker tests public GFCI outlets in community centers - He discovers that many public GFCIs are non-functional, failing to trip at high currents - He warns that GFCI test buttons can work even if the device is faulty. ### Electrical Assessment of a 35-Year-Old House - The house lacks GFCI protection in the kitchen and by sinks - A shared GFCI for washrooms is functional - Speaker finds a functional 5mA GFCI breaker for a non-existent Jacuzzi. ### Advanced Electrical Concepts - Speaker explains how neutral-earth voltage drop causes AFCI trips when connecting a scope's earth to neutral - He observes flattened sine wave peaks from full bridge rectifiers - He emphasizes the importance of proactive replacement of loose outlets.
