Residential Electrician in New Boston, NH: Generator Installation and Backup Power

Why New Boston Is a Generator Town

Most places that need a generator need one for a reason that has little to do with the town. New Boston has a reason that is the town.

Almost nobody here lives in the village. With 326 of 6,108 residents in the village center, nearly every house is on its own lot at the end of its own driveway, served by its own overhead run, with its own well and its own septic. Nothing about that is unusual in the New Hampshire hills, and all of it makes an outage matter more than it does in a town.

When the power goes in a dense town it is a nuisance on a street full of neighbors. When it goes here it is a house on its own, often with children or someone elderly in it, with no water, no heat that needs a fan or a pump, and no reason to think anyone else is looking. That is the case a generator is for.

When the Power Goes, so Does the Water

This is the part of a rural outage people feel first and plan for last.

A drilled well is supplied by an electric pump. No power means no pump, which means no water at the tap, no flushing, and no way to run a washing machine or dishwasher. The pressure tank holds a little, and then it does not. In winter the same outage takes the pump that keeps a frozen pipe from becoming a burst one.

So the well pump is the first circuit on almost every New Boston generator, and it shapes the sizing. A pump has a starting surge well above its running load, and a generator that is sized for the running figure can stall on the start.

The next circuits are usually the furnace or boiler controls, since most heating systems need electricity even when they burn something else, then the refrigerator and freezer, then lighting and a few outlets. The point is to decide what the house actually needs to keep running and size from that.

Gas in the Street, or a Tank in the Yard

The fuel question decides the whole installation, and it should be settled before a unit is chosen.

A standby generator runs on natural gas or on propane. Which one is available depends on the road. Where there is piped natural gas at the street, it is the simplest supply: a connection and a meter with enough capacity. Where there is not, the generator runs from a propane tank, which has to be sited, sized and connected to its own rules.

A house running a generator through a three-day outage uses more fuel than anyone expects, and a tank sized for convenience can run low in the middle of one. The right tank size comes from the load and the length of outage you want to cover, and it should be decided before the pad goes in.

We establish what is on your road at the start. It is the first question we ask and not a discovery during the job, because the answer changes the cost and the equipment.

Where It Goes on a Large Lot

A New Boston lot gives you room, which turns the siting question into a real decision and not a squeeze.

The unit has to sit on a level pad, clear of the house, of openings and of anything combustible, by the manufacturer's distances. Exhaust direction matters relative to windows and doors. That much is true anywhere. What is particular to a large rural lot is the run between the generator, the fuel supply and the house: a longer run means more conductor, more trenching and a bigger voltage drop to allow for.

Snow is the variable people forget. A unit sited in the place where the plow banks, or under a roofline that sheds, is buried in February, which is when it is needed. Siting is decided by walking the property and thinking about where the snow goes, and not from a drawing.

The Transfer Switch, and What You Actually Back Up

A generator is not connected to a house by an extension cord through a window. It goes through a transfer switch, which disconnects the house from the line before the generator is connected, so power cannot flow back out onto the wires and endanger anyone working on them.

A portable generator is the lighter option, and a proper portable hookup with an inlet and a transfer arrangement is about $650. It is for a household that can tolerate starting a machine in the cold and feeding it by hand.

A standby unit starts itself and runs the house automatically, which is the case for a household that is away, elderly, or simply does not want to be doing it at three in the morning. Installed, that is typically $10,000 to $20,000, depending on size and location, with the unit included.

Between the two, a critical loads panel is the way to back up the circuits that matter without sizing for the whole house, which is usually the most cost-effective route on a property with a well pump and electric heating controls.

Sizing From the Circuits, Not the Catalog

The most common mistake is sizing a generator from a number somebody gave you. The right way is to add up what you actually want running.

We list the circuits, assign each a running load and a starting load, and decide which are on the list. The well pump, the heating controls, the refrigeration, some lighting, and perhaps a few outlets. Then the machine is chosen to carry that, with some margin, and no more.

Oversizing costs money twice: in the unit and in the fuel. Undersizing is worse, because the day it stalls on the pump starting is the day you needed it. A calculation from the real circuits is cheaper than either mistake.

The generator sizing tool gives a first answer, and the calculation at the house gives the real one.

Servicing, and Who Repairs It

A generator needs looking after, and this is the question to ask before you buy and not five years later.

Scheduled servicing and everything electrical is ours: the oil and filters on the manufacturer's schedule, the battery, the load test and the transfer switch checked in both directions. When a fault is genuinely inside the engine, it goes to a generator specialist we work with, who sells and services these machines as their trade and administers the warranty.

That is deliberate and it is a benefit: one call, the electrical side handled here, the engine covered by somebody who does nothing else. Generator servicing explains what a visit covers.
