A lot of times, when you read reviews, you wonder whether they're genuine. In this case, I can confidently say this one is. I met Rich and his team at E.H. Haines Electric when I called them for some work on my pool. From the start, they were friendly, professional, and knowledgeable. They arrived when they said they would, completed the job efficiently, and delivered exactly what they promised. I needed Rich to come back a few times for follow-up items, which he graciously did without hesitation. The best way to describe Rich and his company is that they do what they say they're going to do, when they say they're going to do it. I highly recommend Rich and his team at E.H. Haines Electric for any electrical needs. Their professionalism, reliability, and commitment to customer service are truly outstanding.

I am thrilled with the service that Haines Electric provided. I recently purchased a new stove w/convection-electric oven that required a 220 line, which I did not realize when I purchased it. I learned that I needed a new line behind the stove when the plumber was there to install the appliance and hook up the gas. Suffice it to say I was aggravated with myself for not knowing more about what I was buying, but the responsiveness of Haines to get to us as soon as they did in that week, determine the scope of the work and return to complete it within a few days really turned things around for me and this new, significant investment. They are very courteous and highly skilled providers and I highly recommend them.

Rich and Mike from EH Haines Electric Corp did outstanding work for us in our garage and yard. They were punctual, professional, detail-oriented, and the quality of the work was excellent from start to finish. It’s refreshing to work with honest, friendly people who clearly take pride in what they do — highly recommend them.

A family owned business that you can trust. After my husband received a suspiciously high quote from another well known company I came across E.H. Haines. My husband contacted them and the owner of the company came to inspect and give a quote for the installation of an outlet to plug in an electric car charger. The quote was more than 50% less than what the other company quoted and he said they could do the job the next day. On the day of service, two workers arrived and the first thing they did was put booties on to protect the floors. They were so efficient, and explained everything they were doing in advance. In the process of preparing to install the new outlet they found an error the previous electricians did and fixed the problem at no extra cost. The job was completed quickly and they even cleaned up the work area before leaving. They were also kind enough to wait about 15 minutes for my husband to get home from work so he could test out the charger and make sure everything was working correctly. If you are in need of an electrician and want the job done right then do not hesitate to contact E.H. Haines for a professional and cost effective job. You will not be disappointed!

It was our first encounter with Haines Electric and I couldn’t be happier. Rich Haines is a true professional. It is still family owned and they take pride in having their name attached to the business. I’m always one to judge a contractor by his truck The Haines Electric truck was immaculate and he showed up promptly on time. Communication prior to the appointment was superb, as I received a number of text messages to confirm and was able to speak to Rich directly by phone to reschedule. They are by no means the cheapest electrician out there, but their professionalism and attention to detail makes it all worthwhile.

I called with an electrical issue Saturday night and the electrician showed up as promised Sunday morning. He opened the panel, tested the breakers and determined that there was a break in the wiring. He patiently opened light switches, outlets and ceiling lights until he found the break. He made the repair, tested and then retested after everything was put back in place. They now have a loyal customer in me I would happily recommend them to everyone

New Panel Installation

Safe Electrical Panel Installation for Homes, Additions, and Renovations

Electrical panel installation is more than mounting a breaker box. The panel must be properly sized, safely wired, clearly organized, and installed to support your home’s current and future electrical needs.

Haines Electric installs electrical panels for Nassau County homeowners completing renovations, additions, service replacements, new construction projects, and major electrical system improvements.

  • New breaker panel installation
  • Panel replacement during renovations
  • Service equipment installation
  • Fuse box replacement
  • Dedicated circuit planning
  • Panel labeling and final testing

Installation vs Upgrade

A panel installation often involves installing new service equipment, replacing outdated equipment, or setting up a panel as part of a larger project.

A panel upgrade usually focuses on increasing your home’s electrical capacity, such as moving from 100 amp to 200 amp service.

Learn About Panel Upgrades
When You Need Installation

Common Reasons Homeowners Need a New Electrical Panel Installed

Electrical panel installation is often part of a larger home improvement, service replacement, or electrical system redesign. Haines Electric helps Nassau County homeowners plan the right panel setup for the project.

🏗️

Home Additions

New living space often requires additional circuits, capacity planning, and updated service equipment.

🛠️

Major Renovations

Large remodels may require a new panel layout to support kitchens, HVAC, lighting, and appliances.

🏠

New Construction

New homes need properly installed panels designed around the home’s electrical load and layout.

🔥

Panels affected by age, heat, corrosion, water, or unsafe conditions may need replacement.

⚡

Fuse Box Replacement

Older fuse boxes are often replaced with modern breaker panels for safety and convenience.

🔌

New appliances, EV chargers, generators, and equipment may require a better panel setup.

Installation Process

How Electrical Panel Installation Works

A new electrical panel should be planned carefully around your home’s layout, electrical load, future equipment, and safety requirements. Haines Electric keeps the process clear from the first inspection through final testing.

01

Project Review

We review the home, renovation plans, electrical demand, existing wiring, and the reason a new panel is needed.

02

Panel Planning

We determine the proper panel size, circuit layout, breaker needs, and whether additional electrical work is required.

03

Permits & Prep

When required, we help coordinate the installation requirements, prepare the work area, and organize the project.

Replacement Signs

When an Old Electrical Panel Should Be Replaced

Some panel issues can be repaired, but older or damaged equipment may need full replacement. If your panel is unsafe, outdated, or no longer suitable for your home, Haines Electric can install a modern replacement panel.

Heat or Burning Smells

Warm panel covers, burning odors, or scorch marks can indicate unsafe electrical conditions.

💧

Rust or Water Damage

Moisture and corrosion can damage panel components and reduce electrical safety.

⚠️

Outdated Equipment

Older panels, obsolete breakers, or fuse boxes may not meet modern electrical needs.

⚡

Frequent Electrical Problems

Recurring breaker trips, flickering lights, and power issues may point to a failing panel.

Panel Installation FAQ

Electrical Panel Installation Questions

Get answers to common questions about new electrical panel installation, replacement panels, service equipment, and planning electrical capacity for your Nassau County home.

When do I need a new electrical panel installed?

You may need a new panel installed during new construction, major renovations, home additions, fuse box replacement, service equipment replacement, or when existing equipment is outdated or unsafe.

Is electrical panel installation the same as a panel upgrade?

Not always. Panel installation may involve installing new or replacement service equipment. A panel upgrade usually means increasing electrical capacity, such as upgrading from 100 amp to 200 amp service.

Can I replace an old fuse box with a breaker panel?

Yes. Many older homes replace fuse boxes with modern breaker panels for better safety, convenience, and capacity. A licensed electrician should evaluate the full system before replacement.

What size electrical panel should I install?

The right panel size depends on your home size, electrical load, appliances, HVAC equipment, EV charging plans, renovations, and future power needs. Many modern homes use 200 amp service, but every home should be evaluated individually.

How long does electrical panel installation take?

Many residential panel installations can be completed in a day, but timing depends on the project scope, permits, inspections, utility coordination, and whether additional electrical work is required.
