Generator Selection Guide

To determine the right size generator, add the total running watts of all lights, appliances, tools or other equipment to be connected to the generator then allow an extra 20%. Undersizing of the equipment can be avoided by considering all of the loads that will be connected to the generator and by determining the starting requirements of all electric motors Check equipment nameplates to determine wattage requirements If wattage is not shown, but amps and volts are given, the following approximation may be used:
Amps x Volts = Watts
Example: 2.5 Amps x 20 Volts = 500 Watts.

The chart shown below will help you in selecting the proper size generator For portable electric tools and equipment,
check the nameplate rating or use the chart for average requirements Our generators are capable of momentarily
supplying 150% of its nameplate rating, to assist starting electric motors.

Electrical Formulas – Alternating Current
Notes: 1 kilowatt (kW) = 1000 Watts

Single phase Watts = Volts x Amps
Single phase Amps = Watts divided by Volts

Power Factor for Single Phase is 1.0 (Unity)

Three phase Watts = Volts x Amps x power factor x 1.732
Amps = 1.732 x V x Power factor

Typical Power Factor for Three Phase is 0.8

BC's Top 10 Frequently Asked Questions

1. How much does it cost to install a generator?
Installation dependent on proximity to gas & electric services. A typical install within 30 indoor feet of electrical & 10-15 feet of a suitable gas line runs about $1450.00 plus applicable tax and permits.

2. What are the 'hidden' costs associated with buying a backup system?
We tell you before we commence work exactly how much your bill will be. If we miss something on the quote after starting, you will still receive the same quality installation, and we pay for the missed item.

3. How do I know what is the best option for my situation?
Schedule an appointment with us and for $99.00 plus GST, we will evaluate your home, provide you with a load calculation and total price, including applicable permits. If you agree with the price and proceed with an order, we will refund your consultation.

4. What else does Absolute Power Ltd. do?
We supply and install surge protection, power factor correction for Industry, provide net metering, custom sound attenuation along with brokering surplus generators through our power generation network.

5. I want my whole house to be on a generator. What do I need to do?
You need to do a load calculation that includes the size of your home to avoid nuisance tripping on the generator. You then match the size of the ATS to the size of your main disconnect. Remember, if it is a 125 Amp service, you still must use a 200 Amp ATS. If you are not comfortable figuring this out, let APL do it for a refundable $99.00 plus GST.

6. What if my natural gas line ruptures during an earthquake?
Immediately turn off the valve on your gas meter,pull the fuse on the control board, switch the fuel to a suitable Propane tank and move the switch to the LP position (for air cooled Guardian models). Turn on Propane valve and restart.

7. If I place an order, how long can I expect to wait for delivery and install?
If your unit is not in stock, a typical wait for air cooled models is 14 business days of placing your order. Liquid cooled units are typically 4 weeks.

8. How much will it cost me to put my well pump, fridge and furnace on an automatic generator?
Our 8kw Generac guardian series package sells for $2420.00. If the gas and electric service is nearby, we can typically do the install for under $1450.00

9. What areas do you service?
Primarily the BC Lower Mainland. If you live elsewhere, contact us by email to discuss your situation. We can ship and provide instruction anywhere backup or prime power is needed.

10. Do I need a concrete pad?
All air cooled units come with a mounting pad. Liquid cooled units require a 5.5 inch reinforced concrete pad.
