Pool and spa electrical work requires specific expertise and strict adherence to the National Electrical Code. Mid Penn Electric handles pool and spa wiring for homeowners throughout Lebanon, Lancaster, and Dauphin counties — from new installations to equipment upgrades and safety retrofits on older pools.
What Pool Electrical Work Covers
NEC Article 680 sets detailed requirements for all electrical work around pools, spas, and hot tubs — covering GFCI protection, equipotential bonding, conduit materials, disconnect placement, and equipment clearances from the water’s edge. We handle the full scope: new pool electrical installations, saltwater generator wiring, pump and filter circuits, pool lighting, bonding, and safety upgrades for pools built under older code requirements.
We have completed pool electrical work in Hershey, Camp Hill, Palmyra, and Linglestown. In Palmyra, a saltwater generator installation revealed cracked conduit with exposed wiring at the filter pad — a hazard we discovered and corrected on the same visit.

Frequently Asked Questions
What electrical work is required for a new above-ground or in-ground pool?
At minimum, a pool requires a GFCI-protected circuit for the pump, a disconnect within sight of the equipment, and equipotential bonding of all metallic components. Pools with lighting, saltwater generators, heaters, or other equipment require additional circuits for each. All work must comply with NEC Article 680 and be permitted and inspected. We handle the complete installation and coordinate with your pool installer.
My pool was built 15 years ago — does the electrical need to be updated?
Possibly. NEC requirements for pool electrical have been updated multiple times over the past two decades. Pools built before current requirements may lack proper GFCI protection at the panel, updated bonding, or current conduit materials. When pool equipment is being replaced or added — such as a saltwater generator or new pump — it is an ideal time to review the existing electrical and bring it up to current standards. We are glad to assess what you have.
What is electric shock drowning and how is it prevented?
Electric shock drowning occurs when AC current leaks into water near a pool or dock, creating a voltage gradient that causes muscle paralysis in swimmers. It is prevented through proper GFCI protection — which detects leakage current and shuts off power immediately — and equipotential bonding, which eliminates voltage differences between surfaces in and around the pool. Both are required by the NEC and are the primary reasons pool electrical work demands careful, code-compliant installation.
