K Sampson Corp. is a Braintree electrical contractor whose work leans toward the newer end of the trade: EV chargers and home battery storage, alongside everyday residential and commercial electrical work across eastern Massachusetts and Cape Cod. The company says it is certified across Tesla's battery line — Powerwall, Powerwall+, Powerwall2 and Powerwall3 — and on Tesla EV and bi-directional charging, with Enphase battery and bi-directional EV charging certification as well. It also cites OSHA 10, an NFPA hot works certificate, and scissor and boom lift certification, the kind of tickets a crew needs on commercial sites. If you are putting a charger in the garage, adding a battery to carry the house through an outage, or wiring a commercial fit-out, this is a shop set up for that work. Ask which licensed electrician will pull the permit, get a certificate of insurance, and have the panel work priced in writing before the install date is set.
