Manual Transfer Switch Install (portable generator) cost
This guide is for a manual transfer switch that lets a portable generator feed selected circuits safely — not a $6k+ standby package with an automatic switch. National mid: $709.
Materials cover the switch kit / inlet hardware ($300–$650 from cited Home Depot kits). The generator itself is a separate purchase. Interlock kits and true multi-circuit transfer switches are different animals; match the scope on the bid.

indoor manual transfer switch + inlet for a portable generator on selected circuits; portable generator purchase and standby (automatic) whole-house systems are out of scope. National OEWS mean wage used on this page: $34.37/hr (SOC 47-2111).
How the national mid is built
Before you enter a ZIP we use the U.S. OEWS mean wage for Electricians (SOC 47-2111): $34.37/hr (BLS OEWS May 2025). Mid estimate ≈ 4.0 hours × $34.37 × 2.25× markup + materials mid $400 (with a small regional materials factor). Low uses p10 wages × 2.0×; high uses p90 × 2.5×. National planning band: $382 – $709 – $1,563.
Full algebra: methodology. Markup schedule is Fairange’s published assumption, not a BLS figure.
Materials band (cited retail)
Published materials low / mid / high: $300 / $400 / $650 (indoor manual transfer switch + inlet for a portable generator on selected circuits; portable generator purchase and standby (automatic) whole-house systems are out of scope). Shelf checks that shaped the band (see also DATA_SOURCES):
Reliance 3006HDK 30A 6-circuit kit ~$299.95 (202213700); Generac 6377 30A 1-circuit ~$349.99 (203835673). **Portable generator unit not included.** Standby whole-house packages held (materials $6k+).
What usually moves the number
- Circuit count and which loads get backup
- Panel space and interlocking vs true transfer switch
- Cord length and inlet location (outdoors)
- Permit and utility notification rules
- Whether the portable generator is already on site

Manual Transfer Switch Install (portable generator) FAQ
How much does manual transfer switch install (portable generator) cost?
National mid planning estimate is about $709 before you enter a ZIP — labor from BLS OEWS May 2025 Electricians (SOC 47-2111, national mean $34.37/hr) × published hours, plus materials. Local OEWS wages move the band once you type a ZIP.
What hours, materials, and markup do you assume?
Hours 2.0 / 4.0 / 7.0. Materials band $300 / $400 / $650 from cited Home Depot (or similar) retail listings documented in DATA_SOURCES — not lead-gen marketplace averages. Example shelf checks: Reliance 3006HDK 30A 6-circuit kit ~$299.95 (202213700); Generac 6377 30A 1-circuit ~$349.99 (203835673). **Portable generator unit not included.** Standby whole-house packages hel. Labor markup 2.0× / 2.25× / 2.5× (Fairange methodology).
Is this a bid?
No. It’s an educational planning range. Collect at least three written scopes from licensed pros and compare exclusions — permits, haul-away, patching, and code upgrades.
Any rebates or tax credits?
Manual transfer-switch installs are not typically federal-credit eligible. Standby generators sometimes ride utility resilience programs — verify locally; not in this job’s materials band.
