Optional Method Finding Air Conditioning and Heat demand loads Part 2

This is the second video on finding the demand loads using the Optional method. In this video we are just discussing the Heating and Air conditioning part of the optional method calculation. Refer to the National Electrical Code in order to follow along and get more in depth information.
Any specific question can be emailed to me at [e-mail]
Thank you for your support!!

Great instructional video, Craig. I've learned from your channel, subscribing!

Awesome videos. Been using them to help me study.

Sir you videos are very helpful I hope u make u part 3 on optional method

[@jonharrod8690]

This is a great series, very clearly explained. My question is about heat pumps: Often times the ratings list minimum circuit ampacity but not full load amps. Should we use the MCA for demand calculations or do we derate to get FLA? Thanks.

Thanks

Thank you very much brother

CRAIG COULD YOU MAKE A COMPLETE VIDEO OPTIONAL METHOD FROM THE BIGINING TO THR FINAL STEPS. THANKS .

At around 7:00 you use 3 furnaces but 1 blower. Would each furnace not have its own blower? Thank you for the helpful videos. I'm just trying to make sure I didn't miss something

[@johnmozingo5971]

I'm trying to see if you made the 3rd video yet?

[@mjmjersey]

great video where is the third part

I have a central a/c with a c/u at 220v 17 amps and airhandler at 220v 7amp fan with 8k heater
And a mini split at 120v 12a how do I calculate this properly with the optional method

[@frozenturtlefarts1025]

How do you do a 5 ton DX AC? 1 ton should equal 12,000 BTU? So how many VA would it be for 60,000 @ 2000 va/ton, or would it be 5 tons of cooling @2000/ton.

I'm super confused on this question and im getting ready to take my journeyman, any helps appreciated......A one-family dwelling has six 3-kW electric wall heaters (with individual thermostats) and five room air conditioners. Two air conditioners are rated 10.5 amperes at 230 volts, and the others are rated 7.2 amperes at 115 volts. A service calculation is being performed, using the optional method. How many volt-amperes should be included (after demand factors) for the heating and air conditioning? (Assume heater kW ratings equivalent to kVA.).

Hi What does the code say about Electrical Shower Head? Is it allowed?

[@blayton1212]

Nice job, I would to see the code reference for the percentages listed ?

3rd video??

[@johnbriggs7514]

You wrong "more than 4 units" is taken at 40%. I think what you intended was "4 or more units"

[@That_LovelyChina]

You never did the 3rd video!

[@That_LovelyChina]

Is the final answer 125A service?

[@Frank-ox8uu]

So this means that 81.51 VA is equal to an 80 amp size breaker correct
