Why distance matters: voltage drop explained simply
Electricity loses a little bit of pressure as it travels down a wire. Electricians call that voltage drop. Over a short distance, like from a pole at the street to a house in town, the loss is tiny and nobody notices. Over several hundred metres, it adds up.
When voltage drops too far, things start to misbehave. Lights dim when the well pump starts, motors run hot and wear out early, heat pumps and electronics can struggle, and breakers may trip under load. In some cases equipment simply will not run properly at all.
The Canadian Electrical Code sets limits on how much voltage drop is acceptable. Meeting those limits over a long run is the core challenge of a long distance service, and there are a few ways to solve it.
Our solutions: larger conductors or a transformer
For moderate distances, the answer is often simply larger conductors. Thicker wire has less resistance, so less voltage is lost along the way. We calculate the exact size needed based on the distance, your service size and your expected loads.
As distances get longer, oversized wire gets very expensive very quickly. That is where transformers come in. The basic idea is to send power down the long run at a higher voltage, where losses are much lower, and then use a transformer near the house to step it back down to the normal 120/240 volts your home uses.
Depending on the property, the transformer setup may be owned and installed by the utility, or it may be a customer owned installation on your side of the meter. We look at your site, talk with the utility and recommend the approach that makes the most sense technically and financially.
When does a property need a long distance service?
There is no single cut off distance, because it depends on service size and loads. But you should talk with us early if any of these sound familiar.
- Your building site is well back from the road or the nearest utility pole.
- You are building on an acreage, farm or hillside lot with a long driveway.
- You plan to power a shop, barn, second home or cabin far from the main service.
- Your existing home already has dim lights or struggling motors when loads start.
- You want to add big loads like a heat pump, EV charger or hot tub to a home at the end of a long run.
- The utility has told you the connection point is a significant distance from your planned house.
Planning a long distance service installation near Vernon
These projects go best when they are planned early, ideally before your foundation is poured. We start with a site visit to walk the route, look at terrain, rock, driveways, trees and water, and understand where the utility can connect.
Next we do the engineering style math: load calculation, conductor sizing and voltage drop. If a transformer is the better option, we size it and figure out where it should sit. We also talk about trenching, conduit and whether the run should be underground or partly overhead.
You receive a written estimate that clearly separates our work from anything the utility does, along with an explanation of how the pieces fit together.
Working with BC Hydro and FortisBC
Long distance services nearly always involve the utility in a meaningful way. They may need to extend their line, set a pole or pad mounted transformer, or review a customer owned design. Each utility has its own application and design process.
We help you prepare what they need, answer technical questions and coordinate the work on site so trenching, conduit and connections happen in the right order. Utility timelines vary, so we encourage you to start this conversation early in your build.
Underground runs, trenching and conduit
Most long services we install around Vernon are underground. Burying the run protects it from wind, falling trees, snow load and ice, and keeps your property looking clean.
Underground work has its own rules for burial depth, conduit type, warning tape and pull points. We plan the route to avoid septic fields, wells and future building sites, and we leave documentation so you know where the line runs. If you are installing other services such as water or data in the same trench, we can coordinate so everything goes in at once.
Rocky ground is common in parts of the North Okanagan, so we discuss the terrain honestly and work with you or your excavator on the best approach.
Permits, inspections and safety
Service installations require an electrical permit and Technical Safety BC inspections. Our work is led by a Red Seal Field Safety Representative and we are a TSBC registered contractor, so permits and inspections are a routine part of our job.
Transformers and high voltage equipment bring additional safety requirements, including clearances, grounding, protection and labelling. We follow those requirements carefully, because a long distance service needs to be safe and dependable for decades.
Powering shops, barns and second buildings
Not every long run is for the main house. Many acreage owners want power at a shop, barn, greenhouse or guest cabin a long way from the existing service. The same voltage drop principles apply, and the same solutions work.
We can install a properly sized underground feeder to a sub panel, or in longer cases a transformer setup, so tools, heaters, lights and pumps at the far building run as they should. We will help you plan for what you want to do in that building over time, not just today.
Long distance services from Armstrong to Lake Country
Long service runs are part of everyday rural life around Vernon. In the BX, Swan Lake and the Commonage, homes are often set well back on large lots or hillsides. Lavington and Coldstream have acreages and hobby farms where the house and outbuildings are spread out.
In Lumby, Armstrong and Spallumcheen, farm properties frequently need long feeders to barns and shops. Silver Star properties can have challenging terrain and snow considerations. To the south, rural and hillside lots in Lake Country, Oyama, Winfield, Okanagan Centre and Carr's Landing, along with larger properties near Predator Ridge, can also require extended services.
We serve this whole area from our Vernon base, and we understand local ground conditions and utility processes.
Why choose us for your long distance service
A long service is a significant investment, and getting the design right matters. We bring decades of experience, Red Seal FSR qualifications and TSBC registered contractor status, along with a friendly, straightforward approach. We explain the options, show you the numbers and give you competitive and fair pricing.
If your home or building site is a long way from the hydro connection, call us at 250-900-3127 or send a request below. The earlier we talk, the more options you have.
Planning for the loads you will add later
Rural homes tend to grow over time. A shop gets built, a heat pump replaces an old furnace, an EV shows up in the driveway or a suite gets added for family. On a long service run, those future loads matter even more, because the voltage drop calculation depends on how much current flows down the line.
When we design your long distance service, we ask about your plans for the next ten to twenty years. Sizing the conductors or transformer with some room to grow is usually far less expensive than upgrading a long run later. We will show you the options and the difference in cost, so you can make a decision that fits your budget and your plans.
