Losing power during a storm or outage is more than an inconvenience when you have a home office, medical equipment, or a business that cannot afford downtime. Marvel Electricians has installed backup and standby generators across Southern California since 2009, and after 17 years in the trade, our licensed electricians know how to size a system correctly, secure the right permits, and place equipment where it will perform safely for years. If a generator is not what you need, explore our other electrical services to see everything else we handle.

Generator Transfer Switch Installation
A transfer switch is what makes a generator installation safe, and it is required by code for any permanently connected backup system. It isolates your home’s wiring from the utility grid the moment the generator kicks in, which prevents backfeeding power into utility lines, a hazard that can injure utility workers and damage equipment. Automatic transfer switches also handle the switchover without you having to flip anything manually, so power returns to essential circuits within seconds of an outage.
Our electricians size and install the correct transfer switch for your generator and panel, then test the full sequence before calling the job complete. Skipping a proper transfer switch is one of the most common and dangerous shortcuts we see.

Whole House Generator Cost
Whole house generator cost is one of the most searched questions for homeowners considering backup power, and for good reason, since a whole house system is a bigger investment than a small portable unit. The final number depends on generator size, how much of your home’s electrical load it needs to cover, and any site work required for placement and fuel supply. Our electricians walk you through sizing options so you are not paying for more capacity than your home actually needs, or under-sizing a system that will not carry your critical circuits during an extended outage.

Frequently Asked Questions
How much does generator installation cost?
Generator installation starts at $1,500, with the final price depending on generator size, your home’s load, and site conditions.
Do I need a permit for a generator?
Yes, in almost all cases. Our licensed electricians handle the permitting process and coordinate any required inspections for you.
Why do I need a transfer switch?
A transfer switch keeps your home’s wiring isolated from the utility grid during an outage, which prevents dangerous backfeeding and protects utility workers.
How long does generator installation take?
Most residential installations take one to two days, depending on the scope of electrical work and whether gas line work is needed.
Can a generator power my whole house?
It depends on the unit size. Our electricians size the system to your actual load so you know exactly which circuits will run during an outage.
