Standby Generator & Transfer Switch Installation on Long Island
Protect your home or business from coastal nor’easters, hurricane outages, and grid failures with code-compliant automatic transfer switches, portable generator inlets, and whole-home backup power.
At a Glance
Viking Electric & Design installs automatic transfer switches (ATS), whole-home standby generator electrical hookups, and portable generator power inlets across South Shore Nassau, central Nassau, and western Suffolk. Based in East Rockaway, we engineer code-compliant backup systems that protect sump pumps, heating systems, refrigeration, and medical equipment without backfeeding utility lines.

What Our Generator & Transfer Switch Installation Service Includes
Living on Long Island’s South Shore—from Long Beach, Island Park, and East Rockaway to Oceanside, Baldwin, and Freeport—means preparing for coastal storms, high winds, and flood-related utility outages. When the grid goes down, losing power to basement sump pumps, boilers, and refrigerators for even a few hours can result in thousands of dollars in water damage and spoiled provisions.
We install two primary backup power architectures depending on your property layout and budget: fully automatic standby generator electrical systems with Automatic Transfer Switches (ATS) that sense utility loss and restore power within seconds, and heavy-duty 30-amp or 50-amp exterior power inlet boxes paired with manual transfer switches or UL-listed main-breaker interlock kits for portable generators.
Every backup power installation is engineered around strict electrical isolation and load prioritization. A properly installed transfer switch or interlock physically prevents your generator from energizing utility power lines (backfeeding), protecting utility linemen and preventing catastrophic damage to your generator when street power returns.
Backup Power Options Engineered for Long Island Homes
Whether you want seamless automatic switchover for your entire house or a safe plug-in connection for a portable dual-fuel generator, we build backup systems around your critical loads:
- Whole-Home Automatic Transfer Switches (100A / 200A service-rated ATS) that automatically transfer your entire panel and shed high-draw loads like central A/C or pool heaters as needed.
- Essential-Circuit Transfer Panels (8 to 16 circuits) dedicated to sump pumps, gas boilers/furnaces, well or ejector pumps, kitchen refrigerators, Wi-Fi networks, and bedroom lighting.
- 50A (SS2-50 / CS6365) and 30A (L14-30) NEMA 3R weatherproof generator inlet boxes wired to a panel interlock kit, eliminating dangerous extension cords running through cracked windows or doors.
- Elevated coastal mounting platforms and corrosion-resistant PVC-coated or stainless steel conduit fittings designed for high-water-table South Shore lots.
- Commercial backup power cutovers for retail storefronts, medical offices, and server rooms that cannot afford downtime.
Our 4-Step Installation & Inspection Process
Every project is managed directly by founder Robert Neidecker from load calculation through final municipal underwriter sign-off.
Critical Load Audit & Placement Clearance Check
We calculate your starting and running wattage requirements and verify local town/village setback clearances from windows, property lines, and gas meters.
Permit Filing & Plumbing/Gas Coordination
We prepare electrical diagrams for your local building department permit and coordinate with your licensed plumber on natural gas or propane supply sizing for standby units.
Transfer Switch, Conduit & Control Wiring Installation
We mount the Automatic Transfer Switch or manual inlet/interlock, route power and low-voltage control conductors in weatherproof conduit, and bond the system to code.
Simulated Outage Testing & Inspection
We simulate a utility power failure under load to verify automatic transfer timing, load-shed module response, and clean re-transfer before completing final inspection.
South Shore Flood Zones, Setbacks & Utility Rules
Barrier island and waterfront municipalities such as the City of Long Beach, Village of East Rockaway, Village of Freeport, and Town of Hempstead enforce strict zoning setbacks and FEMA Design Flood Elevation (DFE) requirements for standby generators. Electrical disconnects and transfer equipment must be positioned at accessible heights that remain serviceable during coastal storm events.
Additionally, portable generators with bonded neutrals can trip GFCI circuits when connected to a home transfer switch unless configured properly. We verify neutral-to-ground bonding compatibility between your specific generator model and your home’s transfer architecture.
Long Island Standards We Enforce
- NEC Article 702 (Optional Standby Systems) and Article 445 compliance.
- Strict utility isolation for PSEG Long Island, Freeport Electric, and Rockville Centre Electric grids.
- Smart AC load-management modules to power whole-home panels from compact 14kW–24kW standby units.

Generators — Frequently Asked Questions
- How much does it cost to wire a generator transfer switch or standby generator?
- Electrical installation costs vary depending on whether you install a manual 30A/50A portable generator inlet with interlock or a whole-home 200A Automatic Transfer Switch for a standby unit. Call (516) 530-3840 for a comprehensive on-site evaluation and written quote.
- Is a breaker interlock kit legal in Nassau and Suffolk County?
- A main-breaker interlock kit is code-compliant only if it is UL-listed specifically for your exact panel manufacturer and model, installed with a dedicated back-fed breaker retainer clip, and wired to a weatherproof exterior power inlet box. If your panel does not support a listed interlock, we install a dedicated manual transfer switch subpanel instead.
- Can my sump pumps and central air run at the same time on a generator?
- Yes, when sized properly. On whole-home standby systems, we use smart load-shedding relays on heavy 240V circuits (like central A/C condensers and EV chargers) so essential loads like sump pumps and heating always have priority during peak startup surges.
- Do you install portable generator hookups for homes with limited yard space?
- Yes. Many narrow South Shore lots in Long Beach, East Rockaway, and Lynbrook cannot meet the 5-foot window and property-line clearances required for a permanent natural-gas standby unit. A 50-amp weatherproof inlet box with an interlock or manual transfer panel gives you safe, cord-free backup power.
