// YIKAMA-SIKMA MAKINELERI, KURUTUCULAR, ÜTÜ MAKINELERI, ISITICILAR VE PANOLARI NEC, GERILIM DÜŞÜMÜ VE IEC ILE BOYUTLANDIRIN. //
Yıkama-sıkma makineleri, kurutucular, ütü makineleri, ısıtıcılar ve panoları NEC, gerilim düşümü ve IEC ile boyutlandırın. The first step is always the nameplate: voltage, phase, MCA, MOCP, kW, motor current, conductor material and installation limits.
Genel tabloyla değil, her makinenin etiketiyle başlayın.
Akım taşıma, klemens, sürekli yük, motor ve gerilim düşümünü ayrı kontrol edin.
208 V uzun hatlarda kesit büyütmek gerekebilir.
Kurutucu, inverterli yıkama, ütü ve yardımcı ısıtıcıları ayrı değerlendirin.
208 V dryer, 48 A, 145 ft
6 AWG copper is a starting screen, but 4 AWG may be required for a 3 percent voltage-drop target.

MCA
MCA is the minimum circuit ampacity used to size branch-circuit conductors.
MOCP
MOCP is the largest overcurrent device allowed by the equipment instructions.
Continuous load
A continuous load can require 125 percent sizing when it runs 3 hours or more.

1
Read every equipment nameplate and installation manual.
2
Separate resistance heat, motor, VFD, control and support loads.
3
Select conductors with NEC 310.16 and terminal limits from NEC 110.14(C).
4
Check appliance and motor rules in NEC 422 and NEC 430.
Sayısal örnekler
208 V dryer, 48 A, 145 ft
Replace these values with real nameplate data.
6 AWG copper is a starting screen, but 4 AWG may be required for a 3 percent voltage-drop target.
480 V washer extractor, 27 A MCA
Replace these values with real nameplate data.
Start around 10 AWG copper if derating and terminals allow, then verify VFD input and 40 A MOCP.
120 A continuous ironer
Replace these values with real nameplate data.
120 A x 125 percent = 150 A basis before conductor selection where continuous-load rules apply.

Saha senaryosu
- A 208Y/120 V laundry had six 48 A dryers, four 22 A washer extractors, a 36 A booster heater and small 120 V controls. The farthest equipment was 155 ft from the panel.,The revised design moved distribution closer, upsized two long dryer circuits to 4 AWG copper and separated VFD circuits from high-heat circuits. The lesson is that voltage drop can govern after ampacity passes.
- Using a residential dryer rule.
- Ignoring MCA and MOCP.
- Using 90C insulation ampacity as the final value.
- Forgetting raceway derating.
- Skipping voltage drop on long 208 V heat loads.
SSS
What conductor is common for a 60 A dryer?
6 AWG copper is common, but 4 AWG may be needed for 120-150 ft runs or derating.
Are washer extractors motors or appliances?
Use the nameplate MCA/MOCP first, then review NEC 430 for motor and VFD details.
What voltage drop target is practical?
Many designs use about 3 percent branch and 5 percent total, 6 V at 208 V is already 2.9 percent.
Can several dryers share one feeder?
Yes, when simultaneous load, neutral, grounding and overcurrent protection are calculated.
How does IEC differ?
IEC projects use metric conductor sizes and IEC 60364-5-52 installation methods, grouping and voltage-drop checks.
When should conductors be upsized?
Upsize for voltage drop, ambient correction, conductor-count derating, terminal limits or future replacement.
