Panel upgrades get sold on fear more often than they should be. Here is the sober version: most panels are replaced because they have run out of room, because they are a known-defective type, or because something is going in that the existing service cannot carry. Age alone is rarely the reason on its own.
The signs that actually mean something
- No spare spaces. Every slot full, or full of tandem breakers squeezed in where the panel is not rated for them.
- A fuse box still in service. Functional, but you cannot add to it and insurers and buyers will raise it.
- A Federal Pacific Stab-Lok or Zinsco panel. These have a documented history of breakers that do not trip when they should. That is a real replacement reason.
- Heat. A panel that is warm, smells hot, or has discoloured breakers.
- Breakers tripping under ordinary load across multiple circuits.
- A project that needs capacity - an EV charger, a heat pump, a shop, a hot tub or an addition.
That last one is the fastest-growing reason in Alaska right now. People buy an EV, then find out the service will not carry a Level 2 charger. Worth checking before the car arrives, which is why we run a load calculation as part of any EV charger installation quote.
What a service upgrade actually involves
A 100 to 200 amp upgrade is more than swapping a box. It typically includes the panel itself, the meter base, the service mast or lateral, the grounding electrode system, and coordination with the utility for disconnect and reconnect. It is inspected work.
A straight changeout is usually the better part of a working day with power off for a chunk of it. Here that timing is not a small detail - if you are on a well, running heat tape, or heating with a boiler that needs power, we plan the outage window around it, and in deep winter we will sometimes stage the work differently to keep critical circuits alive.
The five things that move the price
| Service size | 100, 150, 200 or 400 amp. Bigger service means bigger conductors, a bigger meter base and more material. |
|---|---|
| Condition of the existing service | A sound meter base and mast keeps the job tight. A corroded base, a damaged weatherhead or an undersized lateral adds work. |
| The run | Overhead versus underground, distance to the utility connection, and whether anything has to be trenched or re-routed. |
| Grounding and bonding | Older installations often need the grounding electrode system brought up to current requirements. It is not optional and it is not expensive to do while everything is open. |
| Location and travel | Road-system work carries no travel premium. Communities reached by air or barge carry freight and travel costs, which we state up front. |
What we will not do is give you a number over the phone and then discover reasons to increase it. We look, we quote flat, and if something behind the wall genuinely changes the scope we stop and show you before carrying on.
Do you need a full upgrade, or a sub panel?
This is worth asking before you spend. If the main service has spare capacity and the problem is simply that the panel is out of physical space, a sub panel in the garage, shop or addition can solve it for considerably less. If the load calculation says the service itself is maxed, a sub panel just moves the bottleneck.
We run the calculation and tell you which one you actually need. Plenty of our panel work has ended with us installing a sub panel for a customer who had been quoted a full service upgrade elsewhere.
What good panel work looks like afterwards
- Every circuit labelled, accurately, in writing you can read
- Conductors dressed neatly, terminations torqued to spec
- Breakers matched to the panel, not whatever fitted
- Grounding and bonding complete and verifiable
- Whole-panel surge protection fitted if you have anything with a circuit board in it
- Inspection passed, paperwork handed over
That last item on the list - surge protection at the main - is cheap when the panel is already open and awkward to retrofit later. Utility switching events and storms do real damage to heating controls, well pumps and modern appliances.
