What Size Generator Do I Need?

Generator sizing is a priorities exercise before it is a wattage exercise. Decide what needs to run together, what can wait and what has a large starting load.

List the essential loads

HVAC, refrigeration, well pumps, medical equipment, lighting and communications often define the minimum useful system.

02

Account for starting current

Motors and compressors can briefly demand much more power than their running rating. That peak must be considered.

03

Use load management intelligently

Automatic load controls can sequence large appliances, reducing generator size without giving up every important circuit.

The useful first step

Get the system understood before the work is sold.

A licensed on-site estimate gives Malco the information needed to explain the real options, cost drivers and safest next step.

Arrange an assessment

Straight answers

Before you book.

Is this a substitute for an on-site inspection?

No. Electrical symptoms can share several causes. An on-site assessment is the safest way to confirm the condition and scope.

When should I stop troubleshooting and call?

Call immediately for heat, smoke, burning odor, arcing, water near equipment or repeated breaker trips. Avoid opening energized equipment.
