100-Amp vs 60-Amp
Still have 60-amp service in your pre-war NYC home? It was plenty in 1950 — but rarely is today. Here's how 60A and 100A compare, and why upgrading is often more than a convenience.
100-Amp
The modern minimum for most homes
60-Amp
Old standard — often undersized today
If you still have 60-amp service, upgrading to at least 100A is usually overdue — for capacity, insurance, and resale.
60-amp service was standard in homes built before the 1960s, when households ran a fraction of today's electrical load. Now it struggles: it limits what you can run, often can't support central AC or modern appliances, is frequently flagged by insurers and home inspectors, and tends to come with an aging panel or fuse box. 100-amp service is the modern minimum for most homes. For many NYC pre-war homes, 100A is the right upgrade — though if you're electrifying (EV, heat pump), it's worth weighing the jump to 200A.
100-Amp vs 60-Amp: the full comparison
| Factor | 100-Amp | 60-Amp |
|---|---|---|
| Capacity | 100 amps (~24,000W at 240V) | 60 amps (~14,400W at 240V) |
| Supports central AC, modern appliances | Generally yes | Often no |
| Typical era | 1960s–today | Pre-1960s |
| Insurance & inspection | Accepted | Often flagged as undersized |
| Usually paired with | Modern breaker panel | Old panel or fuse box |
| Resale | Expected baseline | A noted deficiency |
| Upgrade cost (NYC) | From ~$1,800 (60A→100A) | — |
| Future EV/heat pump ready | Limited — consider 200A | No |
How to choose
✅ Choose 100-Amp if…
- You currently have 60A and run modern appliances
- Your insurer or a home inspector flagged the service
- You want central AC, more circuits, or a modern panel
- You're buying, selling, or renovating
- You're tired of an undersized, aging electrical system
✅ Choose 60-Amp if…
- You're in a tiny apartment with minimal, stable loads
- An upgrade is already scheduled
- A load calculation confirms you're within capacity
- (For most homes, 60A is genuinely undersized today)
The NYC angle
60-amp service is common in NYC's oldest housing, and it rarely travels alone — it usually comes with an aging fuse box or an early breaker panel, sometimes a recalled brand. So the upgrade often solves three problems at once: capacity, outdated equipment, and the insurance flag.
Upgrading from 60A is a panel and service upgrade involving ConEd coordination and a DOB permit, typically starting around $1,800. Before quoting, we run a free load calculation and help you decide between 100A and 200A — if you're considering an EV charger or heat pump, the jump to 200A may be the smarter long-term move.

100-Amp vs 60-Amp: common questions
60A service itself is code-legal, but it's usually undersized for modern households and often paired with an aging fuse box or early panel that may have its own issues. The bigger concerns are capacity (it can't support today's loads) and insurance, which increasingly flags 60A as inadequate. Most homes benefit from upgrading.
100A is the modern minimum and resolves most capacity and insurance concerns. But if you plan to add an EV charger, heat pump, or central AC, 200A gives you headroom and often costs only modestly more at the time of upgrade. A load calculation helps you choose — we run it free.
A 60A-to-100A upgrade typically starts around $1,800, including ConEd coordination, the DOB permit, a new panel and meter equipment, and inspection. Pre-war buildings or difficult meter locations can run higher. Upgrading to 200A is somewhat more. We quote after a free assessment.
Increasingly, insurers flag or decline homes with 60A service as undersized, especially when paired with an old fuse box. An upgrade resolves the issue, and we provide the inspection certificate insurers request. If you've received a notice, that's the time to act.
Yes — increasing your service amperage involves ConEd because it affects the meter and utility connection. We handle all ConEd coordination and the DOB permit as part of the job, so you don't deal with the utility directly.
