LiveWire Electrician

02/About/Residential electrician, Phoenix AZ 85048

We do the amp sums before anyone quotes you a panel.

LiveWire Electrician is a residential electrician in Phoenix. Three years on Phoenix houses, run out of a yard in Ahwatukee, and every job starts the same way: a written load calculation on the service you already have.

A1/Who runs this site

A residential electrician in Phoenix, working out of Ahwatukee.

LiveWire Electrician is the trading name behind livewire-electrician.org. It is a residential electrical contractor: owner-occupied houses in Phoenix, Arizona, nothing else. The yard is at 4605 E Mountain Vista Dr, Phoenix, Arizona 85048, United States, which puts the van in Ahwatukee Foothills, a short run from most of the south side and a freeway drive from the rest of the city.

We have been doing this for three years. That is the honest figure and the only one we use. We will not dress it up as "decades of combined experience", because you are hiring the people who show up, not the sum of everyone's work history.

The work is the work most Phoenix homeowners actually call about. Somebody bought an electric car and wants a Level 2 charger in the garage. Somebody's 1980s house has a 100 amp panel that was fine until the second AC unit, the pool pump and the heat pump water heater all landed on it. Somebody's kitchen keeps tripping. We do that, and we do it on houses only.

Bigger breaker, same wire. That is the fix we get called out to undo most often.

If you are searching for a residential electrician in Ahwatukee or anywhere across Phoenix and you want to know whether you need a panel before somebody sells you one, that is the reason this business exists.

B2/The load-calc habit

You see the arithmetic. Not a guess.

Before we price anything that adds load, we write down what the house already draws and what the new thing will add, and we hand you the sheet.

Here is the problem with how a lot of EV charger and panel jobs get sold in Phoenix. Someone looks at a 100 amp main breaker, looks at a 48 amp charger on the brochure, and says you need a 200 amp panel. Sometimes that is right. Often it is not, and the difference is several thousand dollars and a utility appointment you did not need.

We run the load calculation before we quote. If your 100 amp service can carry a 40 amp charger circuit, we will tell you, and you keep the money a panel would have cost. If it cannot, you see exactly which line pushed it over, and you can decide whether that is a panel, a smaller charger circuit, or a load-management device that sheds the charger when the AC kicks in.

The method is the standard optional calculation for an existing dwelling: general lighting by square footage, the fixed appliances by nameplate, the first 10 kVA at full value and the rest at 40 percent, then the air conditioning and the new continuous load added at 100 percent. Divide by 240 volts and you have amps on the service. It takes us about twenty minutes on site with the panel cover off and a look at the condenser nameplate.

The sheet beside this is a worked example, not anyone's house. A gas-range, gas-dryer, 1,800 square foot place with a 3-ton condenser, which is common across Ahwatukee and the older parts of south Phoenix. It squeaks under. Change the dryer to electric and it does not.

Phoenix adds one wrinkle that the spec sheet does not. Your attic hits 140 degrees in July. Cable in there gets derated, so we size it for August, not for the spec sheet. A run that is legal at 75°F ambient can need the next gauge up once it crosses a summer attic, and that shows up on the quote as a line, not a surprise.

Worked example only. Your figures come from your panel, your nameplates and your square footage. A charger drawing 32 A, on its 40 A circuit, fits here with 3 A to spare; an electric dryer at 5,000 VA would add 2,000 VA after the 40% factor and push it to 105.3 A.

C3/How a job runs

Four stops between your call and a live circuit.

No invented timelines. The only duration we put in writing in advance is this one: most charger installs take one working day. Panels and rewires depend on the utility and the inspector, and we tell you which of the two is holding things up.

  1. STEP 01

    Site visit and load calc

    Panel cover off, main breaker size noted, nameplates on the big appliances read. We measure the run from the panel to where the work goes and check the attic route. You get the load sheet whether you hire us or not.

  2. STEP 02

    Written quote

    Fixed scope, materials named by type and gauge, permit and utility fees on their own lines. If two routes make sense, a circuit only or a panel plus circuit, both are priced so you can compare.

  3. STEP 03

    Permit and install

    We pull the permit. Charger on the garage wall, conduit on the surface, permit pulled. Most single-day installs are done before the afternoon heat. Attic work starts early for the same reason.

  4. STEP 04

    Inspection and handover

    We meet the inspector, walk you through what changed in the panel, label the new breakers and leave the manufacturer paperwork for the charger, panel or devices with you.

D4/Working rules

The rules the van leaves the yard with.

These are habits, written down so you can hold us to them on your job.

  1. Calculation before price

    Nothing that adds load gets quoted until the load sheet exists. A phone estimate for a panel upgrade is a guess, and we do not give guesses with dollar signs on them.

  2. Wire sized for August

    Any cable crossing the attic is derated for Phoenix summer temperatures, not the 30°C table default. On a long charger run that can mean 6 AWG where a cooler state would use 8. It costs more copper. It is the right copper.

  3. Find the fault, not a bigger breaker

    A breaker that trips is telling you something. We trace it to the loose backstab, the overloaded shared neutral or the failed device before we touch the breaker size, and the breaker always matches the wire.

  4. Permits pulled on permitted work

    Panels, new circuits, chargers. If the city requires a permit, the quote carries one, and the fee is itemised at what the city charges.

  5. Fans on fan-rated boxes

    A ceiling fan hung from a plastic light-fixture box will work for a while and then wobble its way loose. Every fan we hang goes on a box rated for it, even when that means opening the ceiling.

  6. The panel gets labelled

    Every breaker we add or move gets a written label. If the existing directory is wrong, we tell you which ones we found wrong.

  7. Old wiring gets named for what it is

    Cloth-jacket wiring with no ground is not a cosmetic problem. It is the reason your new microwave keeps tripping the kitchen. If we open a box and find it, you will hear about it, with the rooms affected written down.

E5/What we do

Five kinds of residential work, and the refusals that go with them.

Each line below has its own section on the services page with materials, spec rows and the price basis.

Scope of work · residential only · Phoenix AZ
WorkWhat it actually involves
Level 2 EV chargersDedicated 240 V circuit to a hardwired wall unit or a NEMA 14-50 receptacle, sized from the load calculation.
Panel upgrades100 A services taken to 200 A, obsolete or recalled panels replaced, utility disconnect and reconnect coordinated by us.
RewiringUngrounded, cloth-jacket or aluminium branch circuits replaced room by room, GFCI and AFCI added where current code calls for it.
Lighting and fansRecessed retrofits, patio and exterior lighting, ceiling fans on fan-rated boxes.
TroubleshootingDead, warm or tripping circuits traced to the fault; whole-home surge protective device at the panel.
Every job priced in writing after a site visit. Nothing on this site is a binding price.

The full refusal list

  • Commercial or industrial work. We do houses. Not shops, not warehouses, not solar arrays.
  • Solar array installation, panels on the roof or the inverter side of it.
  • Generator transfer work we cannot inspect from end to end, including interlock kits fitted by someone else.
  • "Just swap the breaker for a bigger one" to stop a trip. The wire decides the breaker.
  • Hanging a fan on a box that is not fan-rated, even "just for now".
  • Unpermitted panel or service work, whoever is asking and whatever the reason.
  • A panel upgrade quote over the phone without seeing the panel.
  • Burying new circuits on top of known cloth-jacket wiring without telling you it is there.

F6/Reach a person

Ring the number. Someone on the tools answers it.

253-414-2159

There is no call centre between you and the van. If the phone rings out, we are in an attic or behind a panel; leave the address and what is going on, and the call comes back from the same number. Email lands in the same hands, and so do questions about your data, which we answer within 5 days.

Have a charger, a panel or a trip in mind? Send the form with your panel amperage and we bring the load sheet to the visit.
