Circuit breaker and fuse requirements
For main feed protection, choose a circuit breaker or fuse that is large enough to withstand all branch-feed loads for both inrush and steady-state current. See Table 6 on page 39 for the recommended time-delay fuse sizes.
You must choose time-delay fuses and circuit breakers that can withstand inrush current that is up to 15 times the rated input current for 0.01 seconds and up to 10 times the rated input current for 0.1 seconds.
The size requirements for breakers or fuses at your site can change because of the following: n
Local line conditions (such as source and line impedance and voltage fluctuations) n Product inrush characteristics n
Regulatory requirements
Contact a licensed electrician for more information about the codes in your location. 2
The plasma power supply has a factory-installed inrush resistor. If time-delay, high-inrush fuses are not permitted at your site because of national or local codes, use a motor-start circuit breaker or equivalent.
Plasma power supply
You must connect the plasma power supply to one of the branch-feed circuits. Use a separate, primary line-disconnect switch for the plasma power supply. (See Line-disconnect switch requirements on page 40.)
Main power cord requirements
You must supply the main power cord for your cutting system. See Table 6 on page 39 for recommended main power cord size.
The size requirement for the main power cord at your site can change because of the following: n
The distance of the receptacle from the main box n
Local codes and regulations
Contact a licensed electrician for more information about the codes in your location. Line-disconnect switch requirements
A means for disconnecting the cutting system shall be provided according to the installation, safety, and emergency requirements for the local codes and regulations, taking into account the input power requirements.
