What low-voltage wiring to include in a reno?
Planning low-voltage wiring during your renovation is smart — it's much cheaper and easier to run these cables when walls are open. Here's what to consider for a future-ready home in New Brunswick.
Essential Low-Voltage Systems
Ethernet/Network Wiring is the foundation of modern homes. Run Cat6a cable to every room where you might need internet — bedrooms, home office, living areas, and basement. Even with Wi-Fi everywhere, hardwired connections provide faster, more reliable internet for work-from-home setups, gaming, and streaming. Plan for at least two ethernet drops per room, with extra runs to areas where you might add smart TVs or mesh network access points.
Coax cable remains important for cable TV and internet service. Many New Brunswick homes still rely on coax for internet from providers like Rogers or Bell, so include coax runs to main living areas and bedrooms. Even if you're streaming-only now, future buyers may want traditional cable options.
Security system pre-wiring should include door/window sensor wiring and camera locations. Run 18-2 or 22-4 wire to all exterior doors, main floor windows, and potential camera mounting points around your home's perimeter. With New Brunswick's rural areas and seasonal properties, security systems are increasingly popular.
Smart Home Infrastructure
Consider smart thermostat wiring — many older NB homes only have 2-wire thermostat connections, but smart thermostats often need a C-wire (common wire) for power. Run 18-5 thermostat wire to future-proof your HVAC controls.
Whole-home audio pre-wiring using 14-2 or 16-2 speaker wire to ceiling or wall locations in main living areas creates options for built-in sound systems. This is especially valuable in open-concept renovations popular in New Brunswick homes.
Specialized Considerations
Doorbell wiring should be upgraded to handle video doorbells — run 18-2 wire from your electrical panel area to the front door location. Traditional doorbell transformers often can't power modern video doorbells reliably.
For home offices (increasingly important post-COVID), consider dedicated ethernet, coax, and even fiber-optic conduit runs. Many New Brunswick professionals now work remotely and need reliable, fast internet connections.
Installation Tips
Run all low-voltage wiring in separate conduits or at least 12 inches away from electrical wiring to prevent interference. Use a central distribution panel in a basement or utility room as your hub — this makes future upgrades much easier. Label everything clearly with wire tags.
TSANB Requirements
Low-voltage wiring under 30 volts typically doesn't require electrical permits in New Brunswick, but always verify with TSANB for your specific installation. However, any 120V outlets needed to power equipment (like network switches or security panels) will need proper electrical work by a licensed electrician.
The key is planning now while walls are open — adding these systems later means fishing wires through finished walls, which is expensive and sometimes impossible. Consider your family's current needs plus what you might want in 5-10 years.
