Transfer equipment separates generator power from the utility supply. Massachusetts generator-safety guidance calls for a licensed electrician to install a transfer switch; unsafe connections can endanger utility workers and occupants.
Match transfer equipment to the system
A permanent automatic standby installation and a portable-generator arrangement have different needs. A qualified electrician should assess the service, panels, grounding and bonding, selected circuits, and compatibility. Never connect a generator to a wall outlet or improvise a backfeed arrangement.
Decide which loads take priority
Load management can prevent competing demands from exceeding available capacity. Discuss well pumps, heating equipment, sump pumps, and larger intermittent loads. Ask what happens when several loads request power together and how controls behave when normal utility power returns.
Document commissioning
Request labeling, operating instructions, required inspections, and a demonstration of the approved operating sequence. Ask which parts of the home remain unpowered and whether any work changes existing circuits or service equipment. Keep the documentation with your electrical records.
A FEW CONSIDERATIONS
Before we begin.
Can I connect a generator without transfer equipment?
Do not improvise a connection to house wiring. Have a licensed electrician specify and install an approved arrangement for your equipment and local requirements.
How do I request a consultation?
Share your town and project needs through the form. MetroWest Generator Pros is an independent referral site; provider coverage, credentials, and availability must be confirmed. Submission does not book work.
