What to Know Before Installing an EV Charger

Level 2 home EV chargers are the most practical option for most drivers. Here's what the installation process looks like and what your electrician will need to assess.

Key Points

  • Level 2 chargers require a dedicated 240V circuit
  • Your panel must have capacity for the added load
  • Charger location affects conduit run length and cost
  • Permits are typically required — your electrician handles this
  • Most installations are completed in a single day
Commercial

The Business Case for LED Lighting Retrofits

Switching to LED lighting in a commercial space can cut lighting energy costs by 50–75%. Here's what a retrofit project involves and how to evaluate the ROI.

Key Points

  • LED fixtures use 50–75% less energy than fluorescent or HID
  • LED lifespan is 50,000+ hours vs. 10,000 for fluorescent
  • Rebates from utility companies can offset installation costs
  • Better light quality improves employee productivity and safety
  • Retrofits can often be done in phases to minimize disruption
Safety

  • Have an electrician inspect your home before major renovations
Industrial

Why Preventive Electrical Maintenance Matters for Industrial Facilities

Unplanned electrical downtime in an industrial facility can cost thousands per hour. A proactive maintenance program is the most cost-effective way to keep operations running.

Key Points

  • Thermal imaging identifies hot spots before they become failures
  • Loose connections are the leading cause of industrial electrical fires
  • Motor insulation testing predicts failures before they happen
  • Arc flash hazard assessments protect workers and meet OSHA requirements
  • Documented maintenance records support insurance and compliance audits

What to Look for When Hiring an Electrician

Not all electrical contractors are equal. Here's how to evaluate your options and make sure you're hiring someone qualified, licensed, and trustworthy.

Key Points

  • Verify their state electrical license number (MA: check with the Board of State Examiners)
  • Ask whether they pull permits — licensed contractors always do
  • Get a written estimate before work begins
  • Check reviews on Google or the BBB
  • Avoid anyone who quotes unusually low prices — quality work has a fair cost
