Automatic Transfer Switch Installation
Automatic changeover when the power drops and you are not home.
What the job involves
Automatic changeover when the power drops and you are not home. We see this go wrong most often when someone extended an existing circuit instead of running a new one.
Here is how the work actually runs. Sizing is the whole game here. Undersize it and it nuisance trips, oversize the protection and it stops protecting anything.
How we handle it
- Load study to size the unit honestly
- Transfer equipment that isolates from the utility
- Clearances, pad, and exhaust handled to spec
- Tested under load, not just started
Doing this in the White Mountains
Ponderosa country means trees near lines and squirrels in soffits, and both show up as electrical problems eventually.
Elevation, weather, and the age of the housing stock all change how this work goes here compared with a valley city. Equipment ages faster in this sun, monsoon surge is a real load on the system, and a lot of these houses were built as seasonal property and are now carrying full-time demand.
We hold a C-11 commercial license and an R-11 residential license, and the work is done to the code the inspector here actually enforces.
Choosing a fuel out here
Fuel is the decision that shapes everything else about a backup system, and it is more settled by your property than by preference. Natural gas is the easiest to live with when the line is already at the house, because there is no tank to fill and no fuel to go stale. Plenty of properties in this territory do not have that line.
Propane is the usual answer here. It stores indefinitely without degrading, a buried or set tank holds days of runtime, and the same tank often already serves heat or cooking. The tradeoff is that a long outage in deep winter means arranging a delivery on a road that may be difficult.
Gasoline suits a portable unit and almost nothing else. It goes bad in months, it has to be stored somewhere, and refueling a running generator in a snowstorm at two in the morning is the part nobody pictures when they buy one.
Transfer equipment and why it is not optional
A generator connected to a house without proper transfer equipment can backfeed the utility lines. Those lines may have a lineman working on them, and the transformer that steps your service down will step your generator’s output back up on the way out.
That is the reason transfer switches and interlocks exist, and it is why the suspended-cord arrangement that circulates online is genuinely dangerous rather than merely against the rules.
A manual transfer switch or a panel interlock is inexpensive. An automatic transfer switch costs more and earns it if outages happen when nobody is home, or if the household depends on something that cannot be off for hours.
Batteries, generators, and which problem you are solving
A battery system and a generator solve overlapping but different problems. A battery covers a short outage silently and instantly, needs no fuel, and carries a modest load for a limited number of hours. A generator runs as long as it is fed and does not care how long the outage lasts.
Outages up here have a habit of lasting, because the lines run a long way through a lot of trees before they reach most properties. That pushes the answer toward a generator for anybody whose real concern is heat and water through a multi-day winter event.
The combination works well where budget allows. The battery handles the flickers and the hour-long interruptions without anybody noticing, and the generator earns its place on the days that turn into nights.

Surge watts, running watts, and the well pump
Two numbers describe every generator and they are not close to each other. Running watts is what the unit sustains. Surge watts is the brief peak it can absorb while a motor starts, and motors draw several times their running current during that first fraction of a second.
This is why the well pump is the hard load in almost every rural backup system. A pump that runs at modest wattage can demand several times that to break away, and it does it from a standstill against a column of water.
A generator sized on running watts alone will start fine, carry the house fine, and then stall the first time the pump calls. Sizing the surge capacity around the largest motor, then adding the steady loads, is the order that produces a system that works.
Questions we get
Why do I need a transfer switch?
It keeps your generator from backfeeding the utility lines. Without one you are putting power on lines that a lineman may be working on.
What size generator do I need?
Smaller than most people assume, if it is sized to what genuinely has to stay on. The well, the heat, the refrigerator, and some lighting is usually the honest list.
Does it need a permit?
Usually, and there are clearance and exhaust requirements that get inspected.
Are you licensed?
Yes. We hold a C-11 commercial license, number 192532, and an R-11 residential license, number 192533. Both are current and we are insured.
Can you come out after hours?
For genuine emergencies, yes. Burning smells, sparking equipment, water in electrical gear, or a hot panel are not next-week problems.
Towns we cover
Based in Pinetop-Lakeside, covering about forty miles out across Navajo County and the western side of Apache County.
- Show LowOur second base. Panel work and service upgrades on the newer builds off Deuce of Clubs.
- Pinetop-LakesideHome ground. Cabin rewires, fixture work at cathedral-ceiling height, and same-week calls.
- SnowflakeLonger runs out to property on acreage, where the well pump and the house share one panel.
- TaylorOlder service entrances that predate the current code, and the corrections that go with them.
- Heber-OvergaardHeavy second-home territory. Freeze-season calls on places that sat empty since fall.
- LindenBetween Show Low and Pinetop. Remodel wiring and additions on established lots.
- GreerHighest elevation we cover. Generator and backup work for a road that closes in weather.
- ConchoWide-open lots on the Apache County side, often with a long feed from the meter to the house.
- OvergaardPonderosa country. Fixture and circuit work in cabins built across four decades.
- LakesideOlder lakefront cabins where the original wiring was never meant for today’s load.
- PinetopThe cabin core. Small jobs, one outlet or one switch, are most of what we do here.
- White Mountain LakeSeasonal places that need a look before the family arrives and after they leave.
