We’re Super Power Electric — a family-owned electrical contractor based in Red Bank, directly adjacent to Shrewsbury. NJ License #12849. Over 900 five-star reviews. We’ve been working on Shrewsbury homes since 1996.
Shrewsbury is one of the oldest settlements in New Jersey — the Historic Four Corners at Broad Street and Sycamore Avenue dates to the 1660s — but the borough’s housing stock tells a wider story. Along and around the historic district, homes range from 18th-century Dutch-influenced colonials to mid-19th century Queen Anne Victorians. North and east of the historic core, the borough filled in during the 1950s with suburban tract development. And in recent years, newer communities like Heritage Greens, The Ivy, and the Enclave have added modern construction.
Our Red Bank office is literally next door — 5 minutes away, bordering Shrewsbury. We’re closer to most Shrewsbury homes than any other licensed electrical contractor in Monmouth County.
✓ No travel surcharges — you’re in our home territory
✓ Technicians who know the borough — the housing eras, the historic district, the newer communities

We’ve upgraded panels on Broad Street, rewired pre-war homes near Sycamore Avenue, installed generators in Heritage Greens, wired new construction at The Ivy, and put EV chargers in driveways across the borough. Shrewsbury is one of our most active service areas — we’re there multiple times a week.
Shrewsbury's post-war homes — the ranches, capes, and colonials that filled in the borough during the 1950s and 1960s — were built with 100-amp panels and a handful of circuits. That was enough for the era. It's not enough now.
A modern Shrewsbury household running central air, a renovated kitchen with large appliances, a home office, and potentially an EV charger can easily exceed the capacity of a 100-amp panel. We upgrade to 200-amp service, which provides the headroom for current needs and future additions.
For larger homes and new construction — including the custom builds on the oversized lots in the western sections — we install 320–400 amp service with sub-panels as needed.
A panel upgrade is also the first step before adding an EV charger, generator, or hot tub circuit.
Shrewsbury's housing stock spans an extraordinary range — and so do the wiring issues.
Historic District homes (Broad Street, Sycamore Avenue area) — The borough's oldest homes date to the 1700s and 1800s. We've encountered original knob-and-tube wiring, cloth-wrapped conductors, ungrounded circuits, and ancient fuse boxes in these properties. Rewiring historic homes requires careful technique — fishing wire through plaster walls without opening them up, preserving original millwork, and maintaining the character that makes these homes special.
1950s suburban tract development — The bulk of Shrewsbury's housing. Built with 100-amp panels and basic wiring that was adequate for the era. Common issues include undersized circuits, two-prong ungrounded outlets, and in some late-1960s/early-1970s construction, aluminum branch wiring that creates fire risk at connection points.
Pre-WWII Colonial Revival homes — A number of homes from the 1920s–1940s have cloth-insulated wiring that becomes brittle with age, cracking and exposing conductors. Insurance companies are increasingly flagging this during renewals.
We handle full and partial rewires with minimal disruption. If your insurer has flagged your wiring or you're planning a renovation, the wiring assessment is where we start.
Shrewsbury's repair calls divide along the borough's architectural timeline. In and around the Historic District near Four Corners, we troubleshoot problems that come with 18th and 19th-century construction — circuits wired to standards that predate modern code by a century or more, connections made with techniques and materials long since abandoned, and systems that have been partially updated multiple times over multiple decades, creating layers of electrical archaeology behind every wall.
In the 1950s tract development north and east of the historic core, the problems are more uniform: aging breakers, undersized circuits, and wiring connections that have degraded over 70 years. We repair what can be repaired and identify what needs replacement — clearly, honestly, with no pressure to do more than the situation demands.
Shrewsbury is a landlocked borough, but it's still part of the JCP&L service territory that regularly experiences extended outages during nor'easters, summer thunderstorms, and wind events. The borough's mature tree canopy — including the award-winning sycamores along Sycamore Avenue — is beautiful, but it also means overhead power lines are exposed to falling branches and ice loading.
A standby generator provides:
We install Generac, Kohler, and Briggs & Stratton generators. We handle the full process — load calculation, unit sizing, gas line coordination, concrete pad, automatic transfer switch, permitting, and final inspection. Most Shrewsbury homes need a 16–22kW unit for whole-house backup.
Shrewsbury's proximity to the Garden State Parkway (via neighboring Tinton Falls), Route 35, and NJ Transit service at the Little Silver station make it a commuter-friendly borough. And commuters are increasingly driving EVs.
We handle Level 2 home charger installations for Tesla Wall Connectors, ChargePoint Home Flex, and all other makes. The reality for most Shrewsbury homes built before the 1980s: your 100-amp panel doesn't have the 40–50 amps to spare for an EV charger. A panel upgrade is almost always the first step. We handle both in a single visit.
For new construction and the newer communities (Heritage Greens, The Ivy, Enclave), EV charger installation is typically more straightforward — but we still assess the panel capacity before running the circuit.
Whole-House Surge Protection — Panel-mounted protection for electronics, appliances, and HVAC systems. Important for Shrewsbury homes given the frequency of grid fluctuations during storms.
Indoor & Outdoor Lighting — Recessed lighting for kitchen and basement renovations, landscape lighting along driveways and walkways, architectural lighting for the historic district homes, and security lighting throughout the borough.
Electrical Inspections — Pre-sale and pre-purchase inspections. With a median home price around $935,000 and homes selling in about 25 days, a thorough electrical inspection protects both buyers and sellers in this competitive market.
The heart of Shrewsbury — centered on the Historic Four Corners where Broad Street and Sycamore Avenue intersect. This area has been on the National Register of Historic Places and contains 47 contributing buildings. Homes range from 18th-century Dutch-influenced structures (like the Allen House, built around 1710) to mid-19th century Victorian and Queen Anne styles, to pre-WWII Colonial Revival construction. The electrical systems in these homes range from partially updated to dangerously original. Knob-and-tube wiring, antiquated fuse boxes, and circuits designed for oil lamps and a handful of outlets are what we encounter. These homes need skilled rewiring that preserves their historic character.
North and east of the historic core, Shrewsbury filled in during the 1950s with the same kind of post-war development you see across Monmouth County — ranches, capes, and modest colonials on smaller lots, built quickly with 100-amp panels and basic wiring. This is the largest category of housing in the borough. Panel upgrades and circuit additions are the most common work we do in these neighborhoods.
An active adult community of approximately 66 single-family homes. Newer construction with modern panels, but may need customization for EV chargers, home automation, or accessibility-related electrical modifications.

We’re in Red Bank, directly adjacent to Shrewsbury. Most locations in the borough are 5 minutes from our office. For emergencies, we can typically arrive within 20–30 minutes.
Yes. We’ve rewired multiple homes in and around the Shrewsbury Historic District. We use techniques that preserve plaster walls, original woodwork, and architectural character while bringing the electrical system up to current NEC code.
Likely, yes. If your home has a 100-amp panel with original breakers, it almost certainly can’t handle modern electrical loads safely — especially if you’ve added central air, a renovated kitchen, or a home office. We recommend a 200-amp panel upgrade as the foundation for any modernization.
For a typical Shrewsbury home running whole-house backup — HVAC, refrigerator, sump pump, lighting, home office — a 16–22kW standby generator is usually sufficient. Larger homes may need more. We do a detailed load calculation to size it correctly.
