Whole-Home Generator vs Portable + Transfer Switch: The Marin PSPS Call
PSPS season makes this the most-asked question of the year. The right answer depends on your outage exposure, your critical loads, and your budget — here's how we frame it.
The Towery Electric Blog · Marin, North Bay
Cost breakdowns, safety, EV chargers, panels, generators, and the questions our office fields every week. Written from real Marin field experience and reviewed for technical accuracy by a licensed C-10 electrician. No fluff, no lead-gen bait — just the answer we'd give you on the phone.
Quick Answer
This is where Towery Electric publishes plain-English articles for Marin homeowners, buyers, and business owners. You'll find honest cost breakdowns, safety explainers, buyer guides for EV chargers and generators, answers to the questions our phone rings with, and the reasoning behind the brands we install. Every post is written from real field experience and reviewed for technical accuracy by Alex Towery, our licensed C-10 contractor of record.
Cost Guide
The honest version: it's a range, not a number — and the range is driven by your meter location, panel condition, the PG&E service disconnect, and whatever code-correction work surfaces once the cover comes off. Here's how each of those variables actually moves the price.
Filter by the topic you're actually here for. Every article is dated and carries a "reviewed by" attribution — cost and safety content is the kind of thing where the reader is about to make a real-world decision, so we hold it to the same E-E-A-T standard Google recommends for health-or-money content.

PSPS season makes this the most-asked question of the year. The right answer depends on your outage exposure, your critical loads, and your budget — here's how we frame it.

Common in pre-1950 Marin housing stock and a real factor for insurance and resale. What it is, why it matters, and what to check before you close.

Panel headroom, the run from the panel to the garage, and whether you need a load-management device are what actually drive the price. A range, and the variables behind it.

Two different protections, two different jobs, and current code has opinions on where each belongs. A plain-English guide to what protects what — and where.

The single question that saves buyers the most money. When a dedicated electrical inspection is worth it, what it should cover, and what the report can't tell you.

If your Marin home was built or rewired in that window, this is worth ten minutes. What the risk actually is, how it's identified, and the accepted remediation options.

Hardwired or plug-in, single-car or two-car garage, one automaker or a mixed fleet — the honest answer is "this one for this situation." Here's the decision tree.

The panels we trust in the field, the ones we won't put in, and the reasoning behind each. No affiliate picks — just what holds up over 20 years in a Marin home.

Adding a sub-panel is often cheaper — but only sometimes the right call. How to tell whether you're solving the real problem or just deferring it.
Read the article. Make the call. Get a quote written by a licensed C-10 electrician, not a sales script.
Most contractor "blog content" is outsourced — a marketing agency writes 600 generic words about panel upgrades, the contractor never reads it, and the result is useless to anyone making a real decision. This blog is the opposite. Every article starts from actual field experience on Marin projects, gets drafted around a question our office really fields, and is reviewed for technical accuracy by Alex Towery as the licensed C-10 of record. Where a topic touches safety or serious money, we cite primary sources rather than restating them as our own.
Reviewed by a licensed contractor means Alex Towery reads every published article for technical accuracy, current-code alignment, and Marin-specific applicability — and the "last reviewed" date reflects the most recent pass. When code changes or a product line is superseded, the article is updated or retired. We treat stale content as worse than no content.
No step-by-step coaching for unpermitted DIY on energized circuits — that's how people get hurt. No single "best" product pick pretending your situation doesn't matter. No invented statistics. Where an article leads to a decision, it ends the same way: call (415) 419-5960 and we'll work through it with you. The blog exists to make that conversation shorter and better informed, not to replace it.
The Bottom Line
This blog is built for the homeowner, buyer, or business owner who would rather understand their electrical work than just receive a quote for it. Read the article that fits your question. Take what's useful. When you're ready for a real conversation, the number is (415) 419-5960 — you'll be talking to the same people who wrote what you just read.
Every article is drafted from real Marin field experience and reviewed for technical accuracy by Alex Towery, the founder, owner, and licensed C-10 contractor of record (CSLB #989290). We do not publish outsourced, unreviewed electrical content. The byline reflects the author and the reviewer, and the "last reviewed" date reflects the most recent technical review pass.
We publish when we have something genuinely useful to say — usually when a code cycle changes, a product line shifts, a seasonal issue comes up (PSPS planning, storm season), or a question starts coming up on the phone often enough that a written answer saves everyone time. We would rather run a small, current blog than a large, stale one, so older articles get updated or retired rather than left to drift out of date.
No. Cost articles describe realistic ranges for common Marin projects and explain the variables that move the price. They are educational, not a substitute for a written quote on your specific job at your specific address. Panel location, panel condition, service-entrance configuration, utility disconnect requirements, and the local AHJ's plan-review style all change the number. The quote you sign is the binding figure.
For strictly homeowner-permissible work — swapping a faceplate, replacing a fixture on a known-de-energized circuit — the background is helpful. For anything involving the panel, new circuits, service-entrance work, EV chargers, generators, or permitted scope, no. California requires licensed-contractor work for most electrical scope, and unpermitted work carries real consequences: failed inspections, blocked home sales, voided insurance, and genuine safety risk. The blog is here to make you a sharper hiring decision, not to coach unpermitted DIY.
Use the form on the Contact page or call (415) 419-5960 during business hours. Questions that come up more than once tend to become articles, so a good question from one Marin homeowner often helps the next one.
